I don't know why the price all of a sudden crashed. I guess people loose patience and wants something to happen all the time. We have decided what to do and we are just working out some details and then there will be a full update on Sunday with and updated plan.
My guess is that people are losing patience and confidence in MOJO. If i'd be you i would just make a swap to the new blockchain instead of findin a fix to the problem. Also if i would have been you i would've release the fix for the pos issue in this whole time that's not a hard thing and could have been done on the actual chain
I guess the price crashed at the time when the dev seemed to give up the fix and wanted to start a new chain. It was the swap that makes people losing confidence. People may think that the dev is incapable of doing the fix, and doing a swap for such a new coin is quite rare.
You don't see any long standing good coin, such as LTC or Doge, needs to do swapping. Hard forks are fine, but better no swap.
I think the best method is to, as you also said, release the fix for POS issue first, and then the dev can be given more time to fix other issues on the current chain.
Still like to support this coin and hope that the right decision to be made.
