Which altcoin gave you the most profit? And added benefits?
I own Ydentity tokens which helps me in securing my identity while surfing the web. It also generates a risk-identity token based on a simple survey and enables the user to know more about oneself.
Any such innovative coins/tokens? Share your experience!
I do not like altcoins very much,but I believe in the most promising currency, such as Ethereum, in 2018 it shows us a sharp growth after the market correction,I think it pleases everyone
