Bitcore BTX most definately is not a scam. ive been mining and acumulateing BTX for about 6 moths now. Its a hybrid fork of BTC, not to be mistaken for a hard fork. The BTX devs {the same team thats behind BITSEND} created BTX based on the BTC code, but improved it. They took a snapshot of the BTC history and awarded those who held BTC with  BTX on a 1:1 basis. Those who held BTC had to claim theyre BTX, but it was on a time frame which most holders didnt claim. It was then decided BY THE COMMUNITY at the end of that timeframe that any unclaimed BTX should 1 be given to BTC holders on a 1:0.5 basis, 2 any coins left over were to be put aside for airdrops. This was a BTX community decision. So if you held BTC on the 2nd NOV 2017 in a wallet that you control the private keys you are also a BTX holder, you can find instructions on how to get your BTX from the Bitcore website, youtube, Bitcore_BTX twitter, facebook or telegram. The AIRDROPS are predicted to last until the end of APRIL although they could end sooner depending on how many make a move to BTX and register theyre address. The DEVS are very active in telegram, and it is very much a community based project.
