The best crypto for long term investment i think is always BTC, no others can compare to it, due to BTC is the cornerstone of the cryptocurrency market. Besides, now it seems that ETH and BNB are also cryptocurrencies worth taking, especially BNB, i think BNB has more room to appreciate than ETH.
you should be able to be more specific for the intended long term. moreover, you certainly will not know how the market conditions in the long-term planning that you mean.
I am always in a dilemma to determine long-term investment because no one ever knows the state of our assets in the future. although assets are safe from scams market conditions are not always friendly to the plans you make.
all assets mentioned by the OP are very good for investment. but we won't really know which ones will increase.
