Not good at all. Block chain is stacked due to big auto algorithm change pools. What is worse they are mining only in order to dump the coins for profit-BTC.
There must be some kind of protection for this kind of spikes and block chain halts.
Can we implement something like this: if no coin mined in one hour period create dummy-orphaned block and jump to lower difficulty?
I hope its only by accdent and not some kind of attack. The last few days this is really becoming a problem, before it would get stuck for max an hour or so.
Worst case I will make a snapshot of the chain and start a new one on a newer codebase (eg bticoin 14.0)
