Your earning won't stay the same, I guess that differs from day to day, isn't it?
So the block reward will be the same, but the diff rate will decrease? that will let miners get more BTC?
Is that good or bad generally? and specially on BTC price - i guess the price will drop for a while.
Although you can't predict exactly what will happen.
I guess the price will drop, also because BTC-E is probably hacked.
Most of the time the difficulty drops then, so you make more BTC but it's valued less in US Dollars.
As long as miners can earn more BTC per day than most of the miners will be very happy because everyone knows that in the longer run Bitcoin prices will surely go high. So they will mine now and store it for future selling purpose. Currently, no one can predict what will happen after this date but just hold on to your coins.
