Most of the stories here are about people selling BTC to early, I never bough any BTC, so I don't feel that bad about missing out
Ofcourse it really feels bad when you sell your bitcoin too early, imagine, the price of bitcoin on the early months of 2017 was about 1000-1500 dollars but now it is already 9000-11000 dollars. The gap is really big and it makes people who sold their bitcoin feels bad.
