We all know mining with GPU for BTC or LTC or any Scrypt or SHA is not at all profitable. The person already having 3X R9 280 or 290 had invested a lot. Some can't switch to ASIC after such investment and a worst case scenario. Selling for very low rate is not a deal. Any Idea how to make out Return from those fallen ones. Experience shared will be highly appreciated. Any altcoin,or other.........
