I have very little invested in BTC. Most of my crypto investments is mostly in alts and several of them have made some nice gains. Of course, securing our wallet keys is paramount. You either write it down, store it digitally, or both. I have lost some good amount of crypto due to losing my keys and I won't let that ever repeat. I want to rake in a lot of profits this bull run and God forbid that after that, the problem would be that I've lost assess to my wallets.
