I guess that you should avoid all the big VPS providers like AWS,Oracle,Azure,Alibaba Cloud,Google Cloud,Vultr,DigitalOcean,etc.
I know that several hosting providers are more tolerant towards hosting gambling,adult content,etc. but I don't remember their names,since I'm not interested in hosting my own gambling or NSFW website.
Perhaps your should check out for "offshore hosting" providers.
I don't know which one is the most reliable provider.
Maybe there's a way to check the hosting providers of all crypto casinos.
Domain WHOIS lookup or something similar.
Good point. That means VPS's are out (particularly shared VPS's). Fortunately, I know a few offshore hosting providers - once I get the specs I'll ask around to see if they have an appropriate box for this.
