Hello, i have been doing mining with baikal for a few weeks but now i am interested in selling them and buy antminer s9 about 25 of em, i am currently living in the uk so the electricity price is about 0.10-0.12 $ probably of i make a contract as business it will be slightly cheaper.
Is it worth investit for these S9 or should i go to altcoin mining ?
Thank you
