The only danger I see right now is quick ban of cryptos in China, because of too many people switching their focus from real goods production to cryptoponzi madness. You know, thinking that one can easy triple their money, without doing any hard work, just by clicking buttons... Look at how many ICOs do we have per month now, and I bet we can only see a tip of the Chinese iceberg from here. Now imagine that more and more people 'invest' in ICO, drop their real jobs, get burned, etc etc, now we have less food and goods produced+low morale= GG.
