I don't think so. I don't see a need for an encrypted currency. Also a currency needs to remain at the same level all the time. A currency is not an investment. It is a means of exchange.

In order for it to work as a means of exchange, it has to have a stable value. Also, in our modern world, a currency has to be both physical and digital.

The entire world has digital currency. I don't see the problem with it, and I travel across borders all the time.

The degree of energy it uses is also not acceptable.

Also, if you recall, one guy has billions (or was it millions) in his wallet, and he died, and he was the only one who had the code. And nobody else could get access to his money. And some of that money belonged to other people.

I think that all these cryptocurrencies will crash when there is sufficient hardship. Lots of things are going to happen - floods and fires will interfere with internet cables, and people will be offline. They won't be able to access their 'currency' in order to make purchases.

I am, however, curious, as to why you think that cryptocurrency is a good idea.
