Ripple has gotten widespread usage so its not a direct scam, but indirectly it is and here's why:
1. Its pre-mined which only profits the company ripple
2. Its being hyped up as used by banks when in fact the banks are only using the blockchain and not the currency
3. Its not a real crypto, its based on a more or less centralized verification system
So which other coin do you think then will allow for quick under 5 seconds transfers, secure, accepted by financial regulation? And why?
