Should I buy some ripple coins now? Is it worth it?
I heard it was pre-mined and it is not decentralized... it's a bad thing right?
Yes you can buy it, it overtook ethereum and currently the king of Alts. Which means it has proven it has all capabilities to grow further in the market. As a centralised coin it has shown some good signs to the investors and most of the investors are willing to invest in ripple.
