Lots of good ideas here and a pretty nice thread so far
Is there anything this guy wants or needs that money can solve? Because at some point, even if something isn't "worth it", if you have a pile of money and are old then sometimes it can become "worth it". Different house, upgrades on current house, fancy new car, boat, or other toys. Or maybe convenience....lawn service, house service, some gourmet meals prepared in his home a few times per week, weekly in home massage. Or travel, just buy first class tickets and make the trip fun and easy. Maybe playing some iconic golf courses in the US or going to fancy car shows or whatever.
Then he could use something like Vanguard Personal Advisor Services or similar from Schwab or Fidelity. These are super low cost, wildly diversified investments that are going to do just fine and are easy. Like....really easy.
And then as some have mentioned, a few bucks in cryptocurrency and metals might be worth it too. You could put $50-100K in metal and crypto just for fun.
Kinda interested in this forestry option...what is that?
