Because imo, the risk is so great with all crypto, it's better to stay away, but if you're going to get into it at all, I would say put the minimum at risk on a cheap crypto and just let it ride.
It sounds like you plan to hold for very long term anyway, so let's say you put $80.00 at risk on SHIB, which at this moment is at .00001165, this means your $80 buys you about 6,866,952 shibs. If it ever gets to a penny, that $80 will be worth almost $69,000.00, or almost $69 million if it ever gets to a dollar. This "strategy" is pretty much what many of the "bit coin billionaires" did.
The worst that can happen is SHIB goes to zero and you lose $80, but in 10 years or whatever if it goes to a half a penny, or a penny or more, you will cash in huge.
I opened an account with Coinbase Pro
about 8 months ago, it took all of about 10 minutes and I was good to go. The advice I gave you is what I actually did, I put in about $100, which I am willing to loose, and got almost 4 million of the things, at the moment they're only worth about $64.00.
