Venture capitalist Tim Draper said recently that he was worried about the 2% to 4% annual rate of Ethereum. Draper said that Vitalik Buterin (V God) has all, he can say "we only intend to issue 10%." He may not say this, but his followers may. Draper doesn't like the centralized situation presented here, the focus should be decentralization. On the other hand, Draper said that Ethereum has played a leading role in how to build smart contracts. Although he saw many smart contracts built around Bitcoin, he knew that the early pioneering work was done around Ethereum.
