Do holders receive new coins every time Bitcoin forks?

Not necessarily. It depends on whether an independent network is created, whether allocation rules are established, and whether the wallet or custody platform supports it.

Will claiming ECX deduct any of my existing BTC?

The fork itself does not deduct or convert your existing BTC. Do not make payments to addresses claiming that a transfer is required to “unlock the airdrop,” and do not disclose private keys or seed phrases.

If I hold BTC on CoinW, do I need to claim through the project's website myself?

Under the platform's balance-mapping support arrangements, CoinW handles distribution for users who meet the announcement's requirements. Users do not need to complete an on-chain claim through the project's website themselves. Specific eligibility and distribution timing are subject to the official announcement.

Can I participate if I hold less than 1 BTC, or only a BTC Futures position?

The 1:1 ratio refers to quantities and does not, in itself, require you to hold a whole BTC. Whether CoinW sets a minimum amount is subject to its announcement. A Futures position cannot automatically be equated with a BTC asset balance used for the snapshot.

Can I sell ECX on CoinW immediately after receiving it?

Balance-mapping support alone does not establish this. Whether trading will be listed and when deposits and withdrawals will open require the relevant announcements. An airdrop being credited also does not guarantee that a trading market exists.

“I only hold Bitcoin, so why can I receive another coin?” This often happens because of a blockchain fork. A new network can start from Bitcoin's ledger at a particular point in time, retain the corresponding ownership records, and then operate under its own rules. For BTC holders, understanding forks helps explain where airdrops come from and which conditions they need to meet. Take eCash (ECX), which plans to launch its mainnet, as an example: CoinW will support balance mapping to handle the distribution of forked coins to eligible BTC holders. Users can participate by holding BTC on CoinW, without running a node for the forked chain or handling the on-chain claiming process themselves.

1. What Is a Fork? Why Can a Blockchain Take Different Paths?

A blockchain can be understood as a ledger maintained collectively by a network. Which transactions are valid, how blocks are produced, and how assets can be transferred are all governed by a shared set of rules, known as “consensus rules.” When the network changes these rules, or different participants choose to enforce different rules, a “fork” may occur. Upgrades may address scaling, functionality, security, or the network's technical direction. If the new and old rules are incompatible and both sides continue to maintain their networks, independently operating chains may emerge. Source: Bitcoin Developer Guide

Think of a ledger that is continuously updated: everyone shares the same records up to a particular page. From that page onward, two groups start keeping records under their own rules, creating two ledgers that continue to be updated separately. Forks can also be temporary. For example, when two miners find blocks at almost the same time, competing branches may briefly appear. Subsequent accumulated proof of work usually determines which branch the network follows. These temporary branches differ from fork projects that continue operating and create independent assets. Source: Bitcoin Developer Guide

2. How Do Soft Forks and Hard Forks Differ? Do They Always Create New Coins?

When discussing changes to protocol rules, two common approaches are soft forks and hard forks. The key distinction is whether the new rules remain compatible with the old ones.

Comparison	Soft Fork	Hard Fork
Rule changes	Usually narrows the set of previously valid transactions or blocks	Introduces rule changes that old nodes cannot accept
How old nodes respond	Can still regard blocks that follow the new rules as valid, but do not fully enforce the additional restrictions	May reject blocks produced under the new rules
Network outcome	Can maintain a single chain under appropriate activation and support conditions	May result in two independent chains if both the old and new networks continue operating
Whether an independent asset is created	Usually does not create a new coin as a result	May create one, but not every hard fork produces new coins that holders can claim

Source: Bitcoin Glossary

If the entire network migrates to the new rules and the old version stops operating, two assets may not coexist over the long term. When you see news about a “fork,” it is therefore worth asking: Is this simply an upgrade, or a plan to establish an independent network? Is there an allocation arrangement for holders on the original chain?

3. Why Can Holding BTC Give You Access to Forked Coins?

Some fork projects select a Bitcoin block and use the ledger state at that block as the starting point for corresponding balances on a new chain. Recording holdings at that point is commonly called a “snapshot.” Creating or crediting new asset balances under the applicable rules is often called “balance mapping” or a “fork airdrop.”

eCash's official allocation ratio for ordinary holding addresses is 1 ECX for every 1 BTC. For example, an ordinary address holding 0.5 BTC at the mainnet snapshot would have a corresponding balance of 0.5 ECX on the new chain under that rule. The fork itself does not deduct, convert, or transfer the original BTC to the new chain. Source: eCash Official Access Guide

Three points should be kept separate:

Corresponding quantities: The 1:1 ratio refers to coin amounts. It does not mean the two assets have the same price.
The snapshot determines the record: Mainnet allocation is based on the mainnet snapshot. BTC bought or transferred in after the snapshot does not retroactively create eligibility for the earlier on-chain allocation.
Custody affects access: When BTC is held on an exchange, the platform controls the on-chain addresses. Whether users receive forked coins depends on the platform's support for distribution and its specific rules. Source: eCash Guide for BTC Holders

A fork airdrop is an asset allocation on a new ledger. It should not be understood as doubling the return on investment (ROI) on your BTC.

4. What Is eCash? What Does It Aim to Achieve Through a Fork?

eCash, with the asset ticker ECX, is different from the project of the same name that uses the ticker XEC. According to its official introduction, ECX is a Bitcoin hard fork project associated with Paul Sztorc and LayerTwo Labs, with the goal of implementing Drivechains on an independent network. The project currently plans to launch its mainnet on or around October 31, 2026, at Bitcoin block approximately 973,728. The date is an estimate; actual timing depends on block production and the final arrangements. Beta launched on September 19, 2026. The mainnet will use a fresh Bitcoin snapshot, and test balances will not carry over directly as mainnet balances. Source: eCash Project Introduction and FAQ

The idea behind Drivechains is for the main chain to handle foundational mechanisms such as sidechain fund escrow and approved withdrawals, while different sidechains experiment with their own application rules. BIP300 describes the escrow and miner-approved withdrawal mechanisms. BIP301 describes blind merged mining, allowing main-chain miners to commit to sidechain blocks without running the full validation logic of every sidechain. Source: eCash Drivechains Guide

The intended advantage is greater flexibility for application experimentation and the ability for users to choose sidechain features according to their needs. The official project directory covers areas including payments, privacy, digital assets and NFTs, and prediction markets. These are technical directions and development efforts. Actual usage, security, and ecosystem development still need to be assessed after mainnet launch. Source: eCash Sidechain Directory Returning funds from a sidechain to the main chain also requires a lengthy miner-confirmation process. BIP300 describes the relevant withdrawal confirmation process as taking approximately 3–6 months, depending on blocks and voting. Sidechain withdrawals and an exchange's distribution of fork airdrops to users are different processes and should not be confused. Source: BIP300 Specification

5. How Can You Participate in a Fork Airdrop by Holding BTC on CoinW?

For users who hold BTC in exchange custody, support for balance mapping can remove the need to deploy nodes, import keys, and separate assets across the two chains themselves. Users who hold eligible BTC balances at the snapshot time specified in CoinW's announcement can have the platform handle the distribution of forked coins under the applicable rules. Users do not need to send BTC to the project team to claim the airdrop, nor do they need to submit private keys or seed phrases to a claiming website.

If your BTC is currently in another wallet or on another platform, you can review the announcement's requirements and then transfer BTC through CoinW's Deposit page, allowing sufficient time for on-chain confirmations and account crediting. If you already hold BTC on CoinW, check whether the account containing your balance falls within the scope specified in the announcement. CoinW Deposit Instructions The key is to meet the holding requirements at the specified snapshot time. Which account balances count, whether a minimum amount applies, and when distribution takes place are all subject to CoinW's official announcement. Holding a BTC Futures position should not automatically be treated as holding a BTC balance eligible for the snapshot.

6. After Receiving an Airdrop, What Still Needs to Be Assessed Separately?

Receiving forked coins means receiving an allocation of assets on the new network under the applicable rules. This does not, in itself, prove that the project is mature or guarantee that the asset has a stable price or sufficient liquidity. Supporting balance mapping, enabling deposits and withdrawals, and listing an asset for trading are separate service arrangements. CoinW's support for forked-coin balance mapping does not imply a simultaneous commitment to open ECX trading or constitute a guarantee of the project's value or future performance.

In addition, eCash officially discloses that its forked chain applies special rules to certain designated early mining outputs, allowing the corresponding ECX to be spent without the original keys. This raises allocation and governance questions on the new chain. It should not be interpreted as meaning that the project team can transfer BTC on the Bitcoin mainnet, nor does it directly establish that the team can arbitrarily transfer all user assets.

For ordinary holders, eligibility to claim, whether assets have been credited, and whether to participate in the network in the future should be assessed separately using platform records, official rules, and their own judgment.

Summary

Forks explain how a blockchain can follow different rules after a shared history, and why some new networks allocate assets to holders on the original chain. Understanding this mechanism helps distinguish “receiving a new asset” from “receiving a guaranteed return.”

For BTC holders who wish to participate in this ECX fork airdrop through CoinW, the process is: read the platform's announcement → hold eligible BTC at the specified snapshot time → wait for the platform to distribute the assets under the applicable rules. You do not need to handle a complex on-chain claiming process yourself, but should still understand the snapshot requirements and asset risks before participating.

Deposit and Hold BTC on CoinW to Participate in the Fork Airdrop

Risk Notice

Risk	What Could Happen	What Users Should Check
Snapshot and eligibility differences	A deposit has not yet been credited, or the account holding the balance is outside the eligible scope	The specified snapshot time, eligible accounts, minimum amounts, and crediting status
Launch and network risks	Mainnet launch is delayed, early block production is unstable, or a chain reorganisation occurs	Actual project progress and the platform's service arrangements
Price and liquidity risks	Forked-coin prices fluctuate, liquidity is insufficient, or trading is unavailable	Allocation ratios differ from market value; balance mapping differs from a trading listing
Claiming and replay risks	Fake claiming websites steal keys; handling unsplit assets yourself may affect both chains	Use trusted channels only, and never disclose private keys or seed phrases
Rules and governance risks	Special allocation arrangements, sidechain mechanisms, and subsequent rule changes cause disputes	Official disclosures, technical implementation, and actual acceptance by network participants

eCash's replay protection is opt-in; it does not automatically protect every transaction. The fact that the fork itself does not change BTC balances does not mean that using an untrusted wallet or claiming coins yourself is risk-free. Source: eCash Coin-Splitting Guide
