Altcoins are in huge loses, this could be very hard to recover this lose. Some altcoins is almost died from some USD to below 0.01 cents. Bitcoin halving can't change the altcoins season. I believe Ethereum 2.0 could change this season because the highest percent coin is on the Ethereum blockchain.
Indeed, almost all erc20 tokens die because of the bear market and it's very difficult to recover takes a long time, but there is still a moment to recover the price as you said. And of course the project must also be more active in developing products.
