Yesterday I had a chance to read about DPoS, PoS and PoW. STEEM, BTS belongs to DPoS and build by Graphene's blockchain framework. Graphene is the fastest and the real time blockchain technology so far! Actually this is the future. I am not going to sell my BTS, STEEM to anyone! It will be precious in future, that's how I feel it!One more thing! I wish to hear your review about EOS too! Coz I want to hear from genius like you do!@cryptographic,
