This is for pure noobies that don't know what they are doing...
The fees sound very high to me! Why would anyone pay miner fees, pool fees and their fees too!
look at it as a service
you are mining to a base currency (actually only) USD
what ever and whenever you mined your profit in USD stays stable
and you can withdraw the profit to paypal with standard fees
the minersoftware fee is unrelated to the winminer team
they actually also alow to withdraw in eth and btc with comon exchange fees
theire miner configurations are not realy optimum for all nor for advanced miners but this belongs to the countless possible hard and software configurations
you don`t need multiple wallets, you don`t need to know the profitability of all coins, you don`t need to find trustworthy sources for the miner software, don`t need to know anything about configurations you don`t need to know cheap and reliable exchanges ...
but If you do know all this things you can help and improve winminer with qualified feedback and rfe`s.
