Where can the wallet be downloaded from?
Where can I find a legit exchange?
Where can I find a chart showing the exchange rates?
Are there any obstacles or other information I should know before exchanging my money for Electroneum?
At the moment as far as I am aware you can only buy Electroneum with Bitcoin or Ether and only through the token sale which is still live.
As for storing it, until 1st of November it is held on their website until they release their blockchain and wallet.
