Not sure I followed all that, but it seems to me it's the ask wall at mintpal that will hold zeitcoin down. The price at cryptsy will roughly mirror that. While it's currently a little cheaper to buy on cryptsy for ltc at current exchange rates, the fees are higher there and the ltc/btc price is pretty volatile. Aiming the pool to buy from mintpal is the right choice imo.
Yes, but I suggest the best in mine pool early, can do a fair bit. This is more conducive to attract enough miners.
When the price to 8-10, the price gap speak significantly reduced, the mine pool in more computing power, received ten percent of the profits, may be better than now, what do you think.
