If alt-coin mining is going to continue to be profitable this needs to change. 400-500% of BTC isn't shit anymore.
And coinchoose seems like a joke. Right now it says Noirbits is nearly 1500% higher than BTC, but calculating it myself it's actually less than Litecoin which is nearly 3x less. I see this kind of thing on there all the time. Not only that it's killing all the coins thanks to all the coin hoppers.
If you are small miner than coinchose and similar websites can be of some help but if you are medium or big miner than those websites are
not really helpfull and it is so because they are not taking in calculation the volume of buy orders. If current highest buy order price for some
coin is 0.01 BTC and person is buying just 1 coin than out of your 10 coins mined you can sell just one for 0.01 BTC. Dumping your other 9
coins might drop price a lot so once you sell all 10 coins you might end with 0.075 BTC or less instead of 0.1 BTC as stated by coinchose.
I'm pretty sure thats not true, and the sites do take some level of market depth into account. I'm sure sal could chime in if he sees this.
