I see you wrote this article in 2016, I think you have succeeded now with the 20k money you used to have. because in that year Crypto is growing rapidly, and maybe in 2017, you are very happy with your money. but for example, if I currently have 20k, I might use it to trade. I don't use it for long-term investments. because in my opinion the risk of trading today is smaller than making a long-term investment. in my opinion, it's better to earn a little more than to bear a huge risk.
I'm sure he already make a lot of money if he really invested all his money.
Let's say he invested last May 2016 and the price per BTC was just around $450 so he will owned
BTC44.44 , and then hold it for more than a year
waiting for the bull run to come, On december 2017 he sold his
BTC44.44 at $19,500 so that converts to $866,580 less $20,000 and that results to a net profit of $846 580.
WOW!
