What do you mean Bitcoin will end badly. All Bitcoin is a protocol. much like email is a protocol. Email is an alternative to letter writing much like Bitcoin is an alternative to physical money and the way it's is held and used. It will not end badly because it will not end at all. Bitcoin isn't something some one entity can buy and say enough and just end it. Like I said, Bitcoin is a protocol, which has billions and billions actual of fiat money invested in it, that legitimizes it's digital currency. Think of Bitcoin as gold and maybe ethereum as silver or bronze. All other didgital or cryptocurrency will be built on these block-chains, well let's inlcude EOS block-chain as well or even NEO or ADA too. Bottom line is, Bitcoin is the King and it's only just the beginning my friend. It's the technology that will sustain it.
