Its Bitcoin. And there may be two Bitcoins after the BIP148 Segwit starting August 1st. This would be a good thing because it would increase the value of Bitcoin more. Bitcoin and Digital Currencies are here to stay. Its very likey this will replace our current monetary system. So invest, invest, invest, because this will change the world. In a couple years will be saying, "remember when Bitcoin was $3,000 its $20,000 now". And don't forget about the other Altcoins that will make millionaries too.
