Don't beat yourself up over past actions, just learn from your mistakes. You can't wish what was, and Bitcoin couldn't be a currency unless you actually use it sometimes...(same with other crypto.)

I purchased some hotel rooms with BTC when it was worth just a few hundred bucks. I don't mind one bit, because I had a great time in those hotel rooms. ;-)

Keep your eyes out and trust your instincts. This cryptotrain is just getting started. $15k for BTC is nothing...just wait till you see where it goes. (BTC will probably NOT be the highest return from here on out.)
