I really persuade my colleagues to buy bitcoin while it is cheap, i tell them cut some of their salary for bitcoim because i know in the future will have a bull run that may goes up to 20k again or even better than that. This is why i still invest on bitcoin little by little
I also think like you, the price of bitcoin to buy now is the most appropriate and we will wait for its price increase may be equal to or more than 20k $. I think it's a simple thing, we just wait.
