You've made a case for 'queue mining'.........researched it yet?
I have been looking into it and will read the thread more today. The question was asked though what would prevent someone from just having 100s of wallets open?
If someone does that then the cost of running 100 wallets has to be taken into account. Each wallet would have to be mining at 1 thread (CPU), 50% or 100%. I do not see how one can efficiently do 100 wallets. I have passed on your question to Hotcoin developer.
