I'm not a true believer in crypto, but I used to play around with it. I have received a 5-figure USD sum of bitcoin from the MtGox settlement, and I'm considering my options. It is a true windfall. It was worth maybe $100-200 when I used to play daytrader and shop silk road with it.
We are on track for early retirement as it is, but my "smart money" intuition says pay the long-term capital gains and invest in funds, how we do everything else. More money earlier is always good.
My gambler side says to withdraw some maybe, but split the rest into a half dozen likely candidates for someday real world crypto use which may take off. I don't stay up to date on them anymore, so this would take some real research.
The weird Trumpy stuff going on with BTC makes me think it couldn't hurt to hold through the election in case prepper types panic buy it lol.
My wife says it's unexpected so just leave it as a high-risk part of our whole portfolio, but I worry she underestimates the risk and scamminess of it all.
Update: I sold the account down to 0.1 BTC today. I may sell more later on. Thanks everyone for your input.
If you have enough other investments to be comfortable, don't especially want to change retirement timeline etc. and your wife is fine with it, I'd keep it as a potential hedge against a depression that crashes the value of index funds. I would not split it between whichever small crypto projects can sell you a convincing narrative that they have 'moon potential' when your financial circumstances mean you don't really need that anyway and that is specifically what would open you up to the 'scamminess' of crypto.
