I once bought a good amount of Bitcoin last year of October and the price of it are only $600+ and now it's $18,000+ a piece, that's a 3000% increased. I bought also Litecoin earlier this year that averages $4 per coin back then and now it's $266+, a 6,500% increased.

Buyer's remorse, the sense of regret, I really hate that. I experienced and it's awful to realize this kind of things but we need to keep moving forward and accept the fact that it's already done. It's hard to discipline myself not to spend my money to useless things and I am thinking that's just like holding cryptocurrency that has a strong appreciating power over time.
