Well from my perspective saving money for a house is a good idea but investing on cryptocurrency is too risky. Even you invest on stable coins there is no guarantee you will get profit maybe you can just lost your money. We talking about buying a house so maybe you should invest on realistic thing
It's too risky to risk a down payment on a house to invest in the crypto market even though it's bitcoin. It's better not to use the money needed to invest because crypto prices always fluctuate. We have never been able to predict the price of crypto in the next 6 months and I think it's better to use idle money to invest so we don't stress
