> I would classify myself as Boglehead and I believe in the fundamentals of investing in stocks

If you are a boglehead, just stick to no-load, low fee diversified funds. It's the smart way to go for most people. If cryptos are worth investing in, eventually you'll get cryptocurrency exposure via the funds you own or maybe a dedicated crypto fund through vanguard or whomever. I wouldn't take any investment advice on a social media platform.
