Difficulty takes approximately 2 weeks to adjust. Currently, miners are pushing out blocks approximately every 10 minutes. If after the halving day 50% of the hashrate drops of the network, only 50% will be trying to solve blocks with the same difficulty.
Ah, so he's talking about the transition period while the difficulty catches up ? Not the longer term.
Thanks.
Yes, well it needs to adjust basically. I added a PS to my previous post which might interest you.
@Qwizzie, yes that is certainly better than Bitcoin, but still has a risk. Ideally a coin has a smoothing block reward.
