I strongly believes crypto currencies won't disappoint its investors this time,the prices went down but quicky starts to rebound from the deep down and almost recovered half from all time low of this year.Hold crypto currencies more longer then you can test how effective on suing financial crisis situations.
It is unlikely that after such a drop in value, cryptocurrency can disappoint investors.
If you are here with crypto currencies only for few weeks then its disappointment for you.If you bought cryptos since when it was created then you wouldn't worry even if the prices went three figures with bitcoin because you will be still in profits.
