DCA 500$ every two weeks into BTC?

I make decent money, I’m not that well off and have some bills, my btc holdings I would say are better than most, but I can afford to put 1000$ a month into bitcoin. It’s either that or just save my fiat and keep it my bank account. But the thing is I’m trying to save for a house. Do I DCA into btc and basically build interest for me as bitcoin rises and sell when I have enough for a house? I know it’s a riskier play rather than just save all my money and store into a bank account and save until then. But any advice I would appreciate, thank you ahead of time.
