hello i am watching bitcoin for about 3 years now and since last year i took interest into mining.so.. considering the difficulty increase every month is it still worth it to start mining and if yes could anyone possibly tell how much should i invest into it in order to have a profit.also do you think this juge jumps in difficulty will stop over time ? thanks
slow ass!!!
well, there is no any good profitable peace of gear to suggest.
my advice, wait for next generation of miners (like 5-7TH) and be fast with buying and with little bit of luck you'l be in first batch for delivery. also spend as much as you want, only you can decide about amount to spend.
keep an eye on kncminer and black arrow.
