He quite agree with him. My personal opinion is this:
Bitcoin has no true value. Bitcoin is the first decentralized digital cryptocurrency but if you analyze if well you will see that bitcoin currently has no true value. It was initially created allow peee-to-peer transactions without intermedaries and also for easy international payments because bitcoin is not ties down to a country. But here is the fact, all other altcoins out there solves this samw problem and most of the altcoins add value which bitcoin doesn't do. Ethereum solves smart contracts, steemit creates platform for bloggers. What exactly does bitcoin offer different from all other coins?
I see altcoins taking over soon
