Most of the altcoins listed here have already shot up.
Hidden gems are to be looked out for.
What if I told you there is one that I know of which have a strong dev team, working products and is going to get some major marketing attention soon.
..high commits on Github.
..highest number of completed atomic swaps.
..top three in China's CCID rating.
..special mention by @cz_binance.
..crypto-conditions (huh what is that?..exactly.)
..working DEX.
I won't bother to even mention the name. Just google these and DYOR. You'll know where to put your money.
But in fact that none of them have created such a useful product to be used in our real life. These days people are looking for the product will try to dig the potential of the crypto.
It looks so difficult to choose the one that will have filled up of your requirements. I guess there's none.
