Imagine you had to choose only one altcoin for your bag. I can't decide between GRAM, LAW and Libra. The last one is the most questionable: it's popular because of FB but I heard it won't be profitable because of its features of stable coin. GRAM and LAW are great because of its technologies but they are not as popular as Libra. So...yeah that is my problem...And what is your choice?
I do not think that it is right now to argue about those projects that are still at the stage of conversations and are not being traded on exchanges. I would choose between real projects - now I am personally interested in NEO, HUOBI TOKEN and BINANCE. And if we talk about projects that have fallen heavily in price and could have brought more profit, I would especially single out ICON (ICX)!
And i have been having some research on altcoin and I think the best out there are ETH and BNB. ETH has been down for some times now but it is gaining slow gain as well. BNB is on the other hand a new Altcoin in the market unlike ETH and has been gaining huge value. This is because BNB is demanded a lot in the market. And some experts quote that the big fishes in Binance are behind the success of BNB.
