I mean if you look at the tech behind DGB you can easily see why they are the next front runner. The market cap is beyond insane because there are so many people holding through the dumps. This coin will be 3x the price in 2 years minimum.
I know the total supply coin very more and reach to target $1 per coin is very difficult. But I have used it for sending money I satisfied with the function create transaction + confirm fastest in cryptocurrency world I know until now. So, I think why not use it for replace other altcoin or Bitcoin when sending money if just want fast and safe?
