I regretted back in the 2017 ATH when I had nothing to invest in Bitcoin, I think I miss the opportunity then so I decided to accumulate a little I'm earning through signature, I have short a little btc but at least I didn't miss enough on the current bull run.
Oops, bad mate, I lost interest in gambling immediately I had interest in cryptocurrencies, I don't what my balance could have turned into by now. Hope you realize your mistake and gonna take corrections next time.
