What is BTX ? never heard about it . is it another name for Bitcoin . I thought it was only BTC ?
BTX is Bitcore. It has nothing to do with Bitcoin other than at the beginning of the coin there was a snapshot taken of the BTC blockchain and BTX was reserved for owners of BTC to claim. It is not a fork. It is a new blockchain completely independent of the Bitcoin blockchain with new technology and algorithms.
In fact, you are only half right. Bitcore has much in common with Bitcoin. At least that the main code often is Bitcoin's code. Although I do not argue with the fact that Bitcoore developers have done a lot for their coin.
