The bitcoin miners are leaving no stone unturned in preparing for the upcoming bitcoin halving and being well aware of that fact that production cost might double, they're taking the necessary steps to increase profitability. The bitcoin price going up has surely helped their cause. While there's immense optimism, no-one can actually predict the post bitcoin halving prices. It is even more difficult now given the massive unemployment rate and the coronavirus battle the world is fighting. In general, though, there is a growing belief amongst everyone in the community that the event would pay dividends.
The bitcoin halving network mining powerhouses are countries like Venezuela and China, where electricity is subsidized or available for cheap. In these places even if the price isn't favourable they can still manage to make some profit. However, in places where the cost isn't friendly, line Europe, bitcoin miners are relying heavily on the post halving price of bitcoin.
However, this is not to say that the European miners have been sluggish and not completely prepared for whatever is thrown in their way. A survey by Jake Scott of dGen which involves key European halving players provided an interesting insight. It concluded that given bitcoin halving is not out of the blue, the miners get an ample amount of time to prepare for the event, also adding that they've done so by upgrading to the latest equipment and cheap sources of electricity.
