True. But let’s continue the logic chain:
price goes up -> profitability goes up-> miners move over-> difficulty goes up to maintain average block time -> profitability goes down ...
… → miners move out → diff gets decreased.
So, higher price → more miners → more diff == true. My question was the following: how can difficulty go down (miners should go out for that) with high price? What is the reason to go out the coin, which gets more valuable?
May be, I express myself not clear, but I just can’t find clue…
