Am i the only one like this?

I really believe that in the future 5-15 years from now, btc will double or even triple its value. But still im afraid to invest in it. I feel like the moment i will invest on it, it will lose its value for years until to come back, snd i will regreting it daily. And the moment thst it will start recovering i will sell it to not lose my money, and then it will start raising again.

Fk what to do.
