Paypal is digital paying system, and they don't need to be a currency. And they of course don't need to be a cryptocurrency. They have fast speed of transactions, good security and nice usability, what cryptocurrencies don't have.
I joined to their ICO last month, and they raised 21000000$. I thought that it's successfull project, but now on etherdelta(contract: 0x4805e471dd86dc0e3cbe44305391e37e491b579e) it has small activity and last price was 0,18$ (at ICO it was 1$ per 1 token). What is the smart decision, buy or sell?
