– What is the history of this virtual currency?
Segwit2X: One would expect that a project is named “Segwit2x” should be the same project from November having the same core team members and plans. Well, the fact is that the new segwit2x is a totally different thing. While on their website they do claim that they are “refining the classic segwit2x”, this new segwit2x looks really different from what it was in November. All of this leads me to the thought that this new project has little to do with the segwit2x from November. According to the team, segwit2x is a backward-incompatible fork. This means that a new altcoin(B2X or S2X) will be formed; the altcoin will have up to 4MB blocks, segwit support and protection against repeated transactions.
