thx guys
thats not a good idea, then better to buy antimners myself, becouse if i invest hre for example 100 000$ and contract canceled , i'll lose full money and if i buy antminers it should be saved under come back profitable and after will run again
same also this one year plan if after 1 year they don't give you back your money, that means you pay for exsample 100 000$ in once and take back after year 150 000$ total and finish, also you pay evry day maintenance and electrocity fee, so that contract minimum should start from 3 year , otherwise better to buy antminer !
pay 100 000$ ( or 100% of any amount ) in once and take back evry day little little , that is not big $$$ you mean

just 50% more within month , also is risk there, so beter buy antminer or plan should be at minimum 3 year !
