It is good to see variety of services but it includes Brute Forcing too which makes me wonder if the service can be used for evil works ?
Also, for Brute Forcing do you using cloud GPU(s) or you have made any cluster of powerful computing systems ?
Yes ,in theory cracking could be used for nefarious purposes, however I wouldn't accept work like that.
my current main worker is a beast it's great for development in ai and (some)cracking.
I do have clusters. But a bit dated at the moment. Soon GPU prices will keep sliding and I'll be able to retrofit that.
I used to work in a project called 1SPLiTKEY ,it was a brute for vanity wallet application that only worked with splitkey generation.
We offered enough compute power to give most users a free vanity wallet up to 7 digits long.
I let the service run a year before taking it down.(cost prohibited,we literally only had like 3 paid jobs on it)
