do you advice me to order, taking into consideration the delivery is 100 days, and hash difficulty is changing every 2 weeks as per what i heard from a friend.
is it worthy? going to 50GHs/60GHs?
i need your advices for a beginner.
1) Do you feel that bitcoin will increase in price?
2) Do you know the % of increase in difficulty over time?
3) Do you know how many asics are out there now and in the near future?
4) Have you made calculation according to #2 with projected difficulty now and for future increases.
5) Are you sure that you will receive your miner in 100 days.
After you can answer all those honestly to your self then you will have your answer.
