I guess it's possible that we will see bull market only after halving. So maybe it will be the best time for CKM to make IEO?

I can't get it. Where will it be bitcoin halving? And what influence on crypto market will it have?

The Bitcoin block mining reward halves every 210,000 blocks, the coin reward will decrease from 12.5 to 6.25 coins. It will happen 14 May 2020.

So we need to wait 4 months more for the real bull run or do you think, it can start earlier?

I think the start of the bull run should happen a few weeks before like it always happen before any event.

The bull run has been started already with many positive news for Bitcoin and altcoins and it will be only continued, I guess
