Hmmm...okay, I make about 100k per month USD with my business. But now a few of my clients will only pay me in BTC. I think that's great for BTC, but I just don't know what to do with it. I mean, eventually, there's only going to be 21M of these things, right? Should I just hold on to them? I wish I'd bought a shit-ton of them when they were 10 cents...whatever.
If you really don't need the money I would just save the coins on a hardware wallet.
Buy a wallet like a trezor and move your coins on there. That way, you don't have to think about them anymore and they are safe from hacking. You may even want to get multiple ones in case your device fails and you lose your back-up code.
The device costs around 100 usd without shipping, so that is hardly anything for keeping those amounts safe.
