Just patiently wait and hodl it with hope in next bull run sicle maybe some projects will alive and find some investors and mass adoption
I don't think it's going to happen, some of the projects are already buried in the haystack of shitcoins, if we are talking about adoption it should be coins that are already in the market and doing fine, not coins who are long dead, let the dead remain dead do not hope or give false hope to holders.
