Good question. Not sure I would be able to trust Fidelity or the likes when it pertains to your real money. That was the reason we escaped that mess in the first place, but it does pose a question: What do you do when the price gets "up there" and you keep adding it as you DCA. At some point, you will stare at Millions on your phone, if that doesn't scare you I don't know what will....lol. On the flip side, it is a team effort, you can't do it alone, get Family involved or someone who you trust with your life and start there. Get all players educated and agree on a plan. Multiple wallets, multisigs, etc. store keys in a system you trust. (24 or 12 locations?) :-) Have fun this is just getting started....
