Despite all I have said, I still agree with you mate. Cryptocurrency (atleast for me) is the most uncertain business and I love it since I make more money thay my work. Monero difficulty rise from Januari to March is only 500mh to 1 ghs (100% for 2 month), if its only X3 then it just around 2200 units which its to small for Bitmain. I guess they will sells it too since they will have better profit, if they choose to sells the difficulty will last longer. BUT if they make new farm with X3 then it will have exponential growth. With 1000% difficulty in 3-4 months, a $1900 miner still make for 10% from $6000 a month (So $600 a month) until new batch come again it will workout for me. Mine it for 2-3 month and sold it on local market   and with your good luck I feel more optimist
