There are many altcoins in poloniex.com and yobit.net. Especially ZEC, DASH and ETH have good value.
How can we know the altcoins that are at low levels and that are going to rise in the future? Does this have a formula?
What are you paying attention to when investing in any altcoin?
My strategy in buying altcoins nowadays is get them by their Initial Coin Offering (ICO) because their price is very low and have a potential to grow on market but must be careful in investing ICO.
But I keep supporting and trading ETH,DASH and Stratis.
