Bitcoin holders risk losing real BTC if they sell coins from BIP-110 fork, says developer
60-second summary
Bitcoin holders risk losing their actual coins if they sell coins from the BIP-110 fork this weekend, warns a developer, citing the potential for replay attacks where signed transactions from the minority chain can be applied to the main Bitcoin network, making inaction the safest option until the chains are separated, a situation that underscores the risks of forking.
If a minority chain appears this weekend, buyers could replay signed fork-coin sales on bitcoin itself, making doing nothing the safest move until the chains can be separated.
