Central banks can create a Globalcoin, but how they wanna deal with currency fluctuations? Will be there exchanges around the world, where it is traded or will be there a global committee setting the exchange rates?

The other global currency before Bitcoin was gold but was abolished, declared illegal or a barbarous relic.

Bretton Woods failed and who the heck uses SRDs?

I used to use green address until after an update it stopped working altogether, another update later and it's back working but slow as to open, it's empty now so i won't be using it again.

Has someone got a quick explanation of how instant transactions work.

I firstly transferred 0.04 to an address on Mycelium and found out today that it got transfered to another address after 1 confirm. Secondly someone transferred my Bitcoins from both my wallets on my android phone 2.58187103 gambled them in the past 2 days and lost them all early morning to this address 1EdiKj78wUz6rFSmYQBTx9P165vEW27GiD. Can anyone help ? Thats all my Bitcoin gone in 3 days !

Don't think he's here. You could try this: https://www.reddit.com/r/Bitcoin/comments/21d013/wallet32_a_hierarchical_deterministic_bitcoin/

I was wondering if its worth installing and using the bitcoin core client in a tails environment to prevent any security issues etc.

that's why I never gamble with crypto it's more fun go to a cassino anyway.

Cryptocoins-dice.com (investing, not gambling). The admin is legit, I have his phone number and I'll get his ID, we talked a lot and will physically meet (as well as a lot of other Bitcoiners to testify) on the 30th of March. Estimated APR (based on statistics for just-dice): 50% Sure, as long as multisig is not implemented in Monero, there are risks. Not that other assets like GAWminers are better.

As far as I know David never met with him.  They were going to meet last weekend or the weekend before but it got postponed.
