Have altcoins has all the chances to experience growth again. Bitcoin will definitely grow, and behind it, and many altcoins, too. So now it is better not to lose with the choice of coins for investment, because not all of them can grow again.
It is just a matter of choosing the right one and be in patient. We can't move the market as we wanted to do, as it move according to the demand and supply of the market. We know that some investors are still there to help this things our but maybe maybe they just making it step by step not just like the hype they do last 2017. We can choice many coins as we want, but better to look for huge volume and have a good market record.
