You are talking of coins that you can hold has a long term investment, those coins are quite slow in growth now, and one of them is what you have mentioned, I believe that stellar also qualifies, BTT AND BAT are also coins that you can have in your portfolio as against the year you talked about because they have working product, but what I dint understand is why 2022?

Why are you not preparing for the next altcoins bull run which I believe is very close, and if you should be concerned about any coin right now, it is not coins that will stay till 2022, but coins that can give you very high profit in the next alt bull run, and I think some of these projects are still the ones within the limit of top 50 in coinmarket cap. You should really expect much ROI from them for the next bull.
