indeed s9 is the currently best hardware with good $ to hash ratio , in the market, but you need good power supply unit.

good luck.

i bought small amount of bitcoins, because there is onlie service provider who was offering API accessand acepting only bitcoins, so i bout some and then sent it to API provider guy.

i dont usually buy BTC , i am planning to get ASIC and mine some for myself, as a retiremnt plan.

Hi all,

I am new here , i have been planning to get ASIC miner i was going to get Antminer s7, but read threads suggesting, it was not profitable .

besides i am from village area in India and power goes down lots of time and Internet goes down too. but i have access to cheap electricity .

is there live chat feature on this forum, i have lots of questions.

1) do i have to start ASIC after power failuer ? or does it starts automatically and starts mining by itself ?
2) Do i need Air Conditioning system for 1-2 ASIC miners in a room , Temperature here (India) is quite high ?
3) How often difficulty increases ?
4) does the difficulty decreases too ?

So is there ASIC miner which is profitable right now. provided that BTC value stays the same or increases.


Thanks for your time.,

how much investment is needed ?
will it be one time or regular investment ?

and how long before i can see return ?

Thanks
