DigiByte is a great coin, there is no single doubt about that, but is it profitable & worth the investment? I would say it & 100% sure that it's not so profitable as a tradable coin.
No every coin that is having a good community means profit & good ROIs for you.
Yes, I saw those days that it's emerging and even bought it. It's not that competitive anymore but it's still at the top rank so if that's the basis of your choice as an investor, you can take it.
But I'm made my decision that I'll no longer buy or trade this coin.
