I bought at Dec. 2017, for me it is very bad decisions, but I wanted to join the party before it finishes, many predictions were talking about increasing the price higher and higher, people were talking about 100000$ by the end of 2018 and for this you need to speed you entry otherwise you will join late and decrease your profit.
Now I must wait, it is good that I can wait but others couldn't wait and sold out loosing some of their money.
I trust BTC and believe that it will rise again so high, but it is getting this actions late now.
We are waiting.
