Few months back i purchased arround 15 to 16 btc when bitcoin price was 10000$ to 11000$ each btc but now arround 4000$ each btc .Just waiting for 11000$ for each btc than i should leave btc and i can see bitcoin have no future in this time.
Wow,I can't imagine myself investing 150000 USD into bitcoin.This is huge risk.What were you thinking back then?
You should have bought smaller amounts of btc consistently,instead of buying a big amount of btc at once.
Just HODL your btc and wait,there's no other way to get around such loss.Bitcoin might recover after 2 years.
