It doesnt matter what the rank is! for me I like Ethereum Fast transaction, cheap transaction Fee, smartcontract Innovation etc. I like Bitcoin also but due to its slow network and Huge transactioon fee. Im slowly turn to Ethereum now But as we see in Cryptocurrency everything is a surprise and the volatility is high weither  its Eth,waves,or Bitcoin. no one will spare if the market is down. No #1 or #2.
