Go ahead and rent the service for crypto mining and let's see how that works out for you, it's a no for me because that looks like a cloud mining and also a scam, you are better off buying GPU and mining in your basement than this, you will be able to sleep peacefully at night 🌃🌃🌃
I don't have the money to rent it but i found a video on youtube a server with the same graphic cards 8X Tesla V100 and in 2018 they made $28/ hour with this server.
