Is this the Venezuelan petroleum coin?? I didn't realise it was open to investors out the country
It is but this is only the pre-sale (with discounts), which is a private sale reserved to institutional buyers. The public ICO will start on March 19th and will last until all coins will be sold.
We still don't know at what price the Petro will be sold during the public ICO. The white paper says there will be discounts too.
