Does Coronavirus impact Bitcoin halving & future?
Nop, the halving was programed before corona virus comes to this world, and the virus doesn't affect machines, so, the halving will be at the same date with or without CV.
Bitcoin halving needs new mining equipment every time; because once a Bitcoin halving takes place, the existing equipment becomes inefficient for mining. Mining farms then replace the old equipment to be on par with the new algorithm challenges.
The complex in the mining is growing with time, but that and the halving are two different things, miners get affected by halving because the reward is the half, but the mining complexity will keep growing, that's why we need better miners in the long run.
