What happens if Greek banks don't reopen tomorrow? I'm giving them only a 15% chance of opening.
Those banks can't handle even one full day of withdrawals. depositor's haircuts?
What happens after banks are closed for two weeks? Civil unrest? riots?
"OXI" on the referendum is not the end of the story. It's just getting started.
I don't think they will reopen this week. It's all about the ECB and if they will give higher Emergency Liquidity Assistance or not and they use it to make pressure on Greece. With other words: They (presumably) give as much as needed that the banks won't go into complete bankruptcy but not enough to open the banks and/or to remove capital controls.
So, the Greek government is under much pressure. It's like poker... and it will be a blame game. It's possible that there is already a decision for the Greek-bankruptcy. In that case other states will say "no" to any suggestion of the Greeks, the ECB won't give more ELA and time would do the rest. Than they would say: The Greek-government is to blame, because their suggestions were not acceptable and they didn't accept the austerity-plans.
That's just a theoretical scenario but it's possible I think. But either way, there won't be a solution the next days. The german government needs two votings. One for new negotiations and the second to agree or disagree if there should be an arrangement between Greece and the other states and institutes (like IMF).
The other scenario is that Merkel is bluffing but would and will agree the Greek-suggestions... but her problem is that many representatives of her own party won't agree. She would get a majority in any way, but she always wants a "own-majority".
Under the line: The End-result is unpredictable I think, but that they'll make much pressure on greece is predictable and the ELA is a useful tool to hold the pressure. And furthermore: It's not so easy for the ECB to raise it, because it's already against their own law.
Regarding Bitcoin: I don't believe that the Greeks will have much influence on the price in a direct way. But maybe indirect about falling stock-markets and psychology, because the expectation could be that they could raise the price.
Edit: ELA:
