My personal hashrate is ~100x what I had a year ago.
I'm earning about the same BTC as I was a year ago.
I bought more ASICs last week, so my hashrate will double by monday.
The difficulty could very well double by Thanksgiving.
I'll still be earning the same BTC next month as I was at this time last year.
Back 6 months ago, it was very easy to increase your hashrate at a rate larger than the network.
This meant you were earning more.
The difficulty is increasing so fast, it makes this impossible to do. I can't increase my hashrate by 40% every week.
When do you think the difficulty will level off, allowing people to actually grow their operations, rather than just playing catchup?
Stop chasing the network hashrate when you can have better investment investing in BTC
