Should I convert my altcoins to BTC and ETH?

I'm still fairly new to Crypto, only bought some BTC and ETH and the rest I have mined using my GPU on a solar grid, I have mostly mined alt coins via Unmineable and stake them on Binance for se monthly return. Should I exchange these coins for BTC and ETH or leave them for a while until the price raises, or monthly staking drops low?

The alts I am referring to are CAKE as I get a very high stake interest. And then I am holding some ADA, LUNA and SHIB.

Keep long term? Trade now for BTC/ETH? Or wait for value to rise and then trade?

I'd appreciate some input, thanks.

Edit: Thanks for all the replies and insight. So what iv decided to do is once my stake period is over I will convert CAKE, SHIB and the tiny bit of DOGE I have to BTC and ETH (50/50). I will keep my LUNA and ADA. I plan to keep my crypto for long long term, I didn't technically pay for them so have no need for the money so might as well hold forever. I will then continue to use NiceHash to mine using my solar grid until ETH merge happens and I can no longer mine ETH to BTC. Thanks again everyone.
