Hmmm, hard question. I think a gaming notebook would be good for crypo if you are going to mine. But mining is not a good way to earn money nowadays.
Actually mining will lessen the life span of your laptop whether you'll mine through CPU or GPU. It's not just for mining so it's not a good choice if your plan is to mine.
Making wallets with the latest specs would definitely be enough like 9th gen for Intel and the latest for AMD. But I'll be picky with the brand if the purpose would be just for crypto wallets, 1TB of HDD would be enough but if I have other things to do like gaming or rendering, higher specs for RAM and GPU is a must.
