It depends what you want to do with the money, if you would like to get crypto you could put it in the bank and buy it with your real identity but this can raise questions, where did the money come from? what is your job to make this much? if you need to claim it as income you could be subject to tax as well which is not optimal. If you want to get crypto from cash you could buy liquid giftcards and sell them on websites like paxful for crypto for a fee (about 20%)
