My biggest regrets in cryptocurrency in april 2018 because of the dump of bitcoin and ethereum i buy $100 then dump to $70 i lost 30% in just a minute. But now i recovered the trauma of cryptocurrency
I had a similar situation only with bitcoin, then I lost a lot of money in just 5 minutes about $ 1000 , and the price went up then , I think you need to take your time never, I think the price will always recover!
