Because, as it was said, transaction time goes up, fees go up, because of obviously miners close their btc mines and so on
Someone saying something doesn't make it right
Transaction times can go up due to halving in very specific cases, and as I said, this effect can only be temporary and passing. If fees are going to rise, people will start to use some other cryptocurrency. The truth is that Bitcoin copycats (like Litecoin and Bitcoin Cash) are not much worse than the original Bitcoin, at least on purely technical grounds. But seriously, why what I say should have lower weight?
That's an interesting idea. And how do you picture it in practice?
