Might be they didn't allow multiple accounts . If you can get paid using only one account and you can purchase hashing power on 1 account only. Then what is the need of 2 accounts. According to my opinion , try hashprofit . They are doing payments on daily basis. If your balance reaches 0.005BTC everyday, you will get paid every day in your btc wallet.
I do it because I manage investment for a friend wich is not expert with PC so ask me for cloud mining because he likes the idea of mining but will not do any work about it. Personally I get 10% piggyback bonus. I tried changing btc payment address, hope this will work. Bitstamp asked me to know transactions details to solve or tell me what happened but unluckily nobody replies from PBmining email anymore from weeks.. I just bought 2,5 btc to get some hash power but I start worrying about invest on PBmining because of no replies and missed payments. Until 3 weeks ago they always replied in a timely manner and their weekly payments always arrived.. I visited a phisical miner factory in Europe 2 months ago and they told me it is impossible to get pbmining prices on 5 year basis beause it is below costs so it must be a Ponzi and to pay attention about investing there..
I hoped they were wrong.. still hope that but now I don't have elements to be sure about it. I se new contracts of 110Th so Ponzi may last some months.. What do you suggest?
I moved payments to another wallet and changed password hope this work I lost about 0,2 btc with this problem in a week. Previous weeks always worked fine, now problem return every week. I'll let you know if this way it will solve. Someone else encountered same problem?
