After 15 years of being a Bitcoin-only maximalist and about a decade of promoting BIP300 as a soft fork, LayerTwo Labs CEO Paul Sztorc decided to launch Ecash: a hard fork of Bitcoin in which every BTC holder gets free coins. There's a catch, though: while everyone can claim 1 ecash for every bitcoin that they own, Satoshi can only claim half. Meaning that a returning Satoshi will only be able to claim half his coins, while the other half (550k) is currently being sold to investors in order to fund the development and bootstrapping of Ecash. What's more controversial: the hard...
