Select the promising coins from coinmarketcap.com, choose first top ten coins. Coins such as bitcoin, Ethererum, Litecoin, Neo, stellar. These are the most promising coins in the crypto market.
Not everything on top ten is good. Four of the coins on top ten isn't my pick.
I included tether as part of my pick to avoid because its unreliable IMO. And the other ones, I guess you know the reason and the feedback of the community with those coins.
