Bitcoin just forked aka split and created a new coin called bitcoin private, so if you had bitcoin or Zclassic at the time of the fork you would have receive a 1 to 1 ratio of bitcoin private free. To be extract your bitcoin private you must had your cryptocurrency in a wallet that you own the private keys to. SO before the fork a lot of investors would exchange 1 bitcoin for $10,000 to buy Zclassic for $100 each to get 100 free bitcoin private. Then after the fork they would sell off there Zclassic and buy back there bitcoins. This is a good example what people are doing in this space to take advantage of the market.
