my worst experience was in 2018 i bought bitcoin at a price that can be said to be cheap and i still kept some BTC until 2021 yesterday. and after i found out the price of bitcoin reached $60k i came back here and sold half of it i bought a house and a few cars after that i still saved a few more bitcoins for the needs of opening a business and buying some land in my city. i have also told my wife and my parents they are happy and hope i will sell everything soon and start doing business by buying and selling houses in my city. but in fact i put off selling the rest of my bitcoins hoping it would be even higher the price actually went down even more in price and i really regret not selling everything and buying again when the price is low as it is today. and that's when i was really disappointed that i hadn't sold all the bitcoins that i saved and all my goals in opening a house buying and selling business here failed because the money was not enough.
and until now i still feel very disappointed but i did not sell everything i still hold and buy again to wait for bitcoin to print higher ATH in the future
