All of you are saying it is a good idea, but, are you willing to buy some?
I would say most people won't be willing. As good an idea as it might be, a lot of the appeal of cryptocurrency isn't it's use as a currency, but as a speculative investment. When you peg the price of it to a certain asset, such as the price of a barrel oil, there isn't much more reason for people who aren't Venezuelan to invested in something like this. Similar to how there won't be much investment purpose to the cryptocurrency being developed by the Chinese government, since it will be pegged to the RMB.
