- My electricity price is " 0.1$ for each kilowatt "
10 cents / kwh is VERY marginal for being able to even break even on mining, long term.
IMO consider seriously having whatever mining gear you get hosted, or consider moving to an area with a much lower electric cost, before you start mining.
This is also a very good time to "wait and see" as there have been quite a few announcements of upcomming gear that isn't actually being delivered yet - do some research, and consider that you don't have to mine Bitcoin, you CAN mine "altcoins" and often the altcoins are MORE profitable for months to a year at a time for the same amount of $ investment in mining gear.
