Could Greece Take Bitcoin As Its Official Currency?

What Greece need is its own currency which can float properly, so they can export stuff as cheaply as possible.

Anyone can use Bitcoins, they are international.
The problem is they have to be accepted by the seller, and national governments have no control over them.

So yes, the Greeks can use them, but the Greek Government will not be able to regulate their use to their own advantage.

I do not think that the possessors of Bitcoins would be happy that the Greek Government could find a way to piggyback off the Bitcoin currency system. There is a possibility that it could cascade internationally, and bring the whole of the Bitcoin system down with a rather nasty crash.

It would be impossible to know how the currently established international banking system could regulate and agree, as to how avoid a Bitcoin crash. Perhaps they may take no action and just say:
'Good riddance to Bitcoins!', and continue to bandaid the current and badly flawed international banking system.

The problem with the Greek economy is that the population for far, far too long came to assume that they all had a right to their social security system, and successive Government just kept increasing payouts, all based on increasing National debt. It continued to be expedient for those Governments to increasing payouts to the population, just to gain or keep political power.

Perhaps good budgeting by the Government may have avoided this crisis, but too late now. I hope it does not go like Germany in 1922-23.

Now, the Government has no money for the hospital school pension and infrastructure systems and they are all dying with rapidly dimishing funding, because the rest of Europe will not loan them any more money. It is increasingly obvious that they will never be paid back.

And the population still want their pensions and hospitals.
Increasingly, those payments by the Government are forced to be withdrawn.

No money no funny. or No mon, no fun.
