It's unnecessary to start regretting about the opportunities in missed in buying Bitcoin, yeah many of us wish we could reverse the hand of time to meet up with buying at very low price. But the truth is not all wishes can be granted perhaps it's better to focus on the future and buy more rather than regretting without taking any necessary action. That's the mistake most people make in their lives, logically if you remain in regret without taking any necessary action, it obvious you'll just keep the circling around regret.
