I dont know those altcoins you mention if those are have some potential to grow the price and if we can get a profit if Im invested that kind of altcoins. Myabe I need some reasearch first before started to invested and to find out of how useful altcoins is that. And you mention about XRP is one of trusted altcoins that I have right now actually I buy some XRP as of now to take a chance earning from XRP.
