4. I am considering adding a "conservative" multiport that will only switch between NVC, LTC, FTC, MNC and possibly CGB. Would like to hear opinions on this.
This sounds interesting, but what might be interesting is to see some of the other riskier, but more profitable altcoins get added to a superset pool (like NRB, DMD, BTB, STR, ANC, etc). That way you have 3 varieties to choose from.
Most of the 'more profitable' coins are only more profitable because their difficulty is below 0.5, making them undesirable targets for mining by Multipool. They'd be like LKY or ARG, only profitable for a couple minutes and then we'd switch to something else.
ANC I think will be a good add. CAP, CGB and MEC all have single-block difficulty adjustments and the pool spends quite a bit of time on those.
While CAP, CGB and MEC have single block difficulty adjustment, the adjustment itself is limited to only couple of % based on the time it took the network to find a block. ANC on the other hand has wild swings where every adjusment is 29% of the previous difficulty and those adjustments have nothing to do with network speed like they are for CAP, CGB and MEC
