This is showing that miners are not leaving even though price doesn't get pumped after halving, showing price at 600$ range will be floor for next pump.
for the most part of last year bitcoin price was stable at $230 on average and didn't seem to be moving at all. at that price miners were earning 25*230=$5750 per each block they mined and nobody were complaining and no topic on bitcointalk about miners and their future with this price.
now bitcoin price is stable at $640 which means miners are earning 12.5*640=$8000 per each block they mine. now why should they leave?
The profitability of mining is not just based on Bitcoin's value. We also need to consider the mining difficulty. As stated above, in the day the difficulty increased by 1%!
thats true i think that its more dependent on difficulty than just on the bitcoin price, i think halving will not have too much of the effect as the price will most probably grow
Therefore, it could also be said that as the difficulty increases, so may Bitcoin's price.
If new coins are harder to get, many of these coins are guarenteed to go to the three main pools/miners, meaning that, they can put prices up due to the difficulty it is to get the block verified and submitted to the network!
