It is really a win situation on your side and taking the huge risk made a good outcome for you. This is one of the best time to sell again your bitcoin and then wait again for the price of bitcoin to fall again and do the same thing.
Big profits come with big risks. OP managed to get the right timing to buy. Imagine, someone bought at the highest price, then the price slowly fell, then had to determine the right strategy, cut losses or wait indefinitely for the price to recover. that's the importance of basic understanding in cryptocurrency and investment, must use free funds.
don't feel left out if you miss buying cryptocurrency whose price is suddenly good. do not be greedy or panic when you see other people gain a lot.
it's simple, ready to make big profits must also be ready to lose big. only invest what you can afford to lose. use free funds that will not make you fall into poverty if you lose.
