In other words: slower transactions will cost more to send?
he talked about bitshares with 4-6 hours adjustement ... bitcoin would simply be sold off and abandoned if it came to that because 2016 blocks adjustement is two weeks - but only two weeks at normal blocktime. Get the spin?
Network would come to a halt most likely.
My question remains:
does any sudden and harsh drop in hashrate automatically cause this scenario to happen?
Is a single serious set-back in hashrate the end of BTC? Is it really that easy to knock out? OMFG!
What happens when a large pool with let's say 30% of the network has technical problems and just goes offline and hash isn't replaced fast enough? Bitcoin dead?
Looking for some answers here
No, that wouldn't kill Bitcoin because A) most of those miners would point their miners at another pool or solo mine and B) it's usually a safe bet that the pool would come back online eventually. The worst that would happen in that scenario would be an easier (still not easy by any means) shot at a 51% attack.
If we lost a significant amount of hash power just because of miners giving up, then that is a different story. 30% would slow transactions, but the remaining 70% would be able to support the network through a couple of retargets until it equalizes. 60% loss in a few days would be difficult to recover from.
