I’d buy a cold storage wallet, and put it there. (Write the password down and keep it with the drive though!!!) Bitcoin is the least scammy of the cryptocurrencies, and it’s likely to keep going up for a while, since there’s a limited amount. OTOH, regulatory changes–since it’s so electricity intensive to mine–could means it gets banned in many places. Yes, it’s a high risk “investment” (I don’t think of cryptocurrency as an investment at all), but high risk can be part of an otherwise balanced portfolio. Since it was a windfall, you’re not really risking anything by keeping it as bitcoin.
If you don’t already have a financial advisor that has a fiduciary responsibility to you, you might want to consider getting one, and asking their advice.
