Suggest any under the radar coins which will go big soon.
My suggestion is XRD, Radix
I will not advise you to invest in any of the two coins you have mentioned here because these two coins are not well known to me and even if they are well known I will never advise you to invest in such coins. Because you may not be very successful with these coins it is best to go with the most likely coins that will be successful. And it is always better to go with bitcoin and ethereum as your risk is much less if you go with all these coins.
most users who name coins to invest with are also those holders, hence, they are suggesting what they have in he hopes that some people will buy such alts and make some noise also. in such a way that it can give more interest to traders.
