I'm not agree my friend, bitcoin most valuable for sure, however there are ripple wich going strong with each day for example or EOS, I think people still believe in alts.
By the way, "Ripple" yesterday began a sharp upward movement and showed + 20%. With its capitalization, this is an important indicator. It is possible that now is the moment of trend change on the crypto market, and we are waiting for growth!
Now is the time to buy!
They announced new technology that's why it happened, by the way a lot of altcoins going up right now, so it seems people believe in alts.
