My biggest takeaway from the past few weeks is that POW based distributed cryptocurrency is a bit like communism; it only works on paper. The reality is that, even with Bitcoin, the power to stave off attacks has consolidated to a few big players. The massively distributed protocol and massive power usage is a huge wast at this point. If your gonna need a few big players anyway, might as well build a trusted circle from the start and eliminate the rest of the waste. The coins that can actually be used for day-to-day transactions are vulnerable to attacks. The largest and most secure player, Bitcoin, has reached the point where transaction fees are too high and speeds to slow; nobody takes it anymore. Where does it go from here? I predict governments are gonna crack the whip and altcoins, along with ICOs, will be a footnote in history.
