i really regret it, yes i hold Bitcoin, Ethereum and Binance, all of them went down deep,
and it was terrible to see, more than -50% that I can, I don't know this is a nightmare for me.
The thing is you'll only regret when bitcoin will go down, you didn't sell at peak because of your greediness. Man, it's alright, live with that and learn with your experience, bitcoin is very unpredictable, but if you follow your target, selling should not be the price even if it's lower than the ATH as long as you make a profit.
