why more secure? if you don't need the money. higher risk can mean higher return. but if you are going to hold this the whole time. I would suggest getting coins with maximum supply

This is my portfolio. I plan to leave it untouched for at least 10 years. I know it could go to zero, but I could also see outrageous gains. It's money that I don't need right now. "Moonbang" is what I'm going to do. Any tips to make it safer?
