Just look for solid dev teams building real products. Don't get caught up in the shilling, look at fundamentals and be patient.
OP is asking "Which Currency" , meaning he does not understand how to find one and you are just shitposting about to look for Solid Dec and real products things that is obviously what we all know from the start.
but the thing is is it really easy to find one?
because if this is truly happening then we are all Richer by now.
Op stated his own list of cryptocurrencies for long term invesment, its just shows that he did his own research already to come up with that list.
Anyway I agree that its not easy to determine if the project is solid or has potential (especially those new ones sprouting). Thus established coins are still the best pick (like bitcoin, eth and bnb) when it comes to long term investment.
