I have tried it, it is fun to be able to play games while earning a penny. Can players really get hex tokens by playing for free forever? I have seen many game projects like this, in the end "deposit" is something that is required, without such action, players could never withdraw and turn what they have produced in game to the money.
That is the plan. There may be limitations on the minimum amount to withdraw to deter cheat and farming accounts but that's something we'll have a look at when we reached that point in the development.
