We have it made with investing in the stock market - contributing monthly to a Vanguard index fund will give you better results than most traders and managed funds.
Crypto seems to be a bit more difficult, and it's still so speculative. I have seen more discussions about portfolios and asset allocations in the last couple months, which is a good sign that a lot of people are looking at crypto as a way to invest in projects/companies, not necessarily to get rich quick.
