I'm thinking about it.How come that coin with the first name bitcoin is already a fake bitcoin? It means in crypto space it's easy to identify the real and fake bitcoin.Because in fiat money Fake money is almost the same with the original one that's why sometimes it's difficult to identify it fast. I think those fork coin are not really fake bitcoin because they have separate systems which does not interact with Bitcoin instead the creator of that put that name just to make sure that their coin will also known and can attract people because they have a bitcoin name at first. It's just like a marketing strategy.Well,whatever it is, for me there is only one Bitcoin (BTC) in crypto world.
