Damn, this post really hits me hard. I have been having these what ifs for a long time now, even at 20k peek(ATH) I was so sad in selling at 14k+. And just imagine now how devastated I am looking at the price right now while thinks ng back on how cheap I sold my possessions back then. And bitcoin isn't even the only one I sold early I also sold altcoins too early and some with losses. even my dogecoin key was forgotten since I didn't care enough about it to take it seriously. phew. I should really start forgiving myself.
There is no need to be regretted in every action you have done because the one who knows that time when you sell is of course you. it could be that you are selling because of a need that you cannot avoid which must be done immediately because other needs are waiting.
It looks like the events you have experienced are of course many who are also doing the same as you, especially since we know that last year a pandemic swept the world until now. clearly the need for a decent life is a priority even though we will find out that the bitcoin we hold will go up. because there is no other alternative to do at that time. so it's okay and we really think it's not our luck.
because the development of bitcoin continues to increase every day since the 16th 17th 18th until today a renewable ATH is formed, there is still a chance to save little by little because time is still long and bitcoin is still increasing.
regret will not be able to finish what you did at that time, keep the spirit.
