Well, they are liars and thieves. They will not let you to collect enough Satoshi to get above the minimal withdrawal limit. As long as you upgrade you mining machines they will let you but when you want to accumulate some Satoshi in your balance suddenly the mining machines start to break and they will take back all your profits to repair them. Sometimes, although the broken machine is under warranty, when you repair it your balance is reduced. Liars and thieves...
