Always alt coins depend on bitcoin movement. And alt coins also touch their ATH during Bitcoin's bull season. And yes, many investors still believe in Doge Coin. Doge coin may show a bull run again, in this case we need to have patience and faith and invest for long term, only then we can get maximum profit.
Altcoins depend on Bitcoin making a new all time high but doesn't really depend on it because altcoin bull run is impacted by dominance of Bitcoin decreasing while that of altcoins in general increase. In fact, the bull run is when altcoins are making run of their money, that's when you know that yes indeed we are in bull run but right now, such has not happened yet.
I think that Bitcoin is still fighting to nake a new leaf, it's not coming down and its not going up and usually when this continues for long time, it gain a huge momentum and make a new run for a new all time high. Hopefully Bitcoin does that very soon so we can see altcoins run for their money.
