We live some hard times, for those who invested after june 1st 2017, probably like me didnt make to much profit, i trust that this bubble will dissapear so have faith this time next year u will laugh. If u can invest all the money in BTC is the most secure coin, and the most less affected in this buble. BTC is now the most old coin and it proved that is a refference coin, i dont think ethereum will be the first one not this year, maybe next one.
All the best my friend!
