Well, I understand what are you going through because I walked the same path last summer. I invested serious money in my wallet and everything started to going down and after a few months a through it's over with the crash, but it crashed again. I was nervous like you now probably. And at some point, it started to rise. My gains were unbelievable and everything was like my friend told me how it will be.
So at the end of the March and upcoming months, you will see a rise and in the summer you will experience crash again. This is a normal thing in the crypto market. I know it's hard to just sit there and wait, but that is the only thing you can do now if you invested money. Just wait.
And the most important thing is to remember how this works because there will be more ups and downs. Anyway, whats the point if Bitcoin stays at 10000$ for 100 years.
