Minexsystem has an own wallet: https://minexcoin.com.
You can also withdraw your coins from the bank instantaneously. We do not call banks in general scams even though our fiat is printed when we deposit (fractional reserve banking). As I stated above my purchase price for Minexcoin is very low, so it is definitely money I can loose. But, if you do a due diligence (check out software, read wp/ roadmap etc) and are still sceptical, please tell me, and I will take it into consideration.
