The top pools are all well run and used to pay out on regular basis. Unfortunately since May 9th a single (private) miner had been mining 98%+ of all MBC coins.  The developer has exploited a weakness in the new RFV2 algorithm and updated his miner to take advantage of said weakness. After 18 days, even with updates to the CPU and NVidia miners, the rest of the MBC community (99.99% of us) are left to fight for the remaining 1%-2% of all new MBC coins created.  While I applaud the developer for his extensive knowledge and coding skills, this much control in the power of one pool and one person is extremely unhealthy for any coin.  I would suggest mining elsewhere until the playing field is leveled.
