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.
Based from the lists above, bitcoin will always be the best for long term investment. It will always be the crowd's favorite. But bnb and ethereum are still next to bitcoin. Well bitcoin and these two altcoins have different utility case so when it comes to long term investment, i think these 3 coins should always be on the top.
However, since the market is very unpredictable so i'm not closing doors to other coins because they might be more profitable in the near future, who knows? The fact that you know how to manage your coins, then it will still generate profits in the long run.
