I've got about 2.5m coins at the moment.
Mainly working on Icon and IF flipping, ICONs work best because of the lack of supply. So you need a decent bank to start with, looking to buy them at the right price on bid and the relisting them on BIN for a quick flip. So for example I brought a Paul Scholes for for 290k ish on bid and then sold at BIN for 338k, so a profit of 30k ish after tax, another was a Vieri I only made about 5k on that. You have some good one and some average ones, but do enough a the profit builds quickly.
I try not to hold on to them to long as price
