I think the demand for or interest in crypto has nothing to do with finding the best place for OP's business, they are looking for data entry employees not blockchain related, I do not want to hurt anybody's feelings but I'd pick Egypt simply for the following reason.

1- The pay rate is probably the lowest.
2- The population is more than the other listed countries combined and thus the manpower is a lot higher.
3- The country is pretty safe to a reasonable degree.

Some of the other countries you mentioned have some of those points in place too, tax in Alegria and Libya are probably the lowest, and starting a business is perhaps easier in Morocco than in Tunisia or Algeria, but overall I think Egypt would be the best.

By the way, why not hire people online instead of having to open up an office all that?
