Dentacoin is dedicated platform developed for the dentists with a separate blockchain and it keeps pushing the market. But, this hasn't made any bid progress as expected. Dentacoin
DENT is a platform that is being developed for the Mobile operator serving. This was much expected and it reached among the top 50 rank on coinmarketcap. Later this turned downwards and the team isn't much on promotion and it is kinda manipulated market.
I tried to sign up with it and received some dent tokens which I then use later on to purchase mobile internet data and call credits. It was nice at first until their rates increases, resulting for me to not use them. I think that was the start of their fall but who know's? Maybe they will make an epic comeback later on.
