Generic advice about investing. If you have a date you need to liquidate on then you need something that isn’t volatile. If your investment (stocks, crypto currency, collective plates, gold) dips when you need to withdraw, you lose the ability to ride out the dip.
if you had a longer horizon, say two years, something with wild swings may be more appropriate. On a direct advice point, I wouldn’t invest near term house buying money on crypto, or highly speculative stocks. Loses aren’t loses until you cash out.
