Vertcoin is taking off, due mostly to its asic-resistant algo. Anyway we can get a pool made that mines Vert and pays in BTC? Work on that Terk! You could corner the market if you're the first out with that.
For a multipool, because Vertcoin halves your hashrate, if you calculate BTC per Mh/s, it's still better to mine other altcoins and dump them. Vertcoin is about 0.08 BTC per Mh/s (halving your hashrate). Multipools are 0.05-0.08 BTC per Mh/s.
If you wanting to speculate that Vertcoin's value will go up, then you will need to join a dedicated pool and not convert to BTC like multipools do.
Well that's my guess and shitty calculations.
