As BTC seems to be in BULL run so all the investors are now only focusing the BTC but as soon as the market stabilized ALT coins will also start go up.
The coins markets change in time. Sometimes when one coin has a bull run other coins have bear run but this can then reverse in that the bears runs becomes bulls runs and the opposite as well. We will see alts going into bull runs many times over the days the weeks and the months coming.
