Legendary, could you please explain what this means for the average user like me
can I still send BCH to an exchange to sell for BTC or is it over already? ty
You will be able to sell once the network starts moving.
As the difficulty will decrease in the adjucted blocks, eventually blocks will be found at the same rate as Bitcoin (even if not many people would mine it) so exchanges will accept deposits and withdrawals.
Once the difficulty adjusts you will be able to send but I think exchanges will always require an extremely high number of confirmations due to the low hash rate making any major bitcoin mining pool able to perform a 51% attack if they wanted to.
