WHY? coz of NICEHASH (and others autominers, but NH pay directly in THEIR PRICES) ..... in moment when you find a coin, which seems profitable and its 1 of these algos, there is 99,9% chance of nicehash already knows it and switch for that .... and profit si gone in couple of minutes
Hmm... but If I am checking 24h or even longer time difficulty for revenue not current one then I should get decent information no?
