I don't know what to say except that the most secure long term investment is Bitcoin. All the others may fail. How did Verge and Pundi X got on that list is beyond me.
Great list you have found there. I'm investing into or doing swing trade with the first 7 coins on the list. The rest if the coins on the list I would not invest into, not saying you can't do some great trades with them.
For really long time holding, for a longer periode than just 2019, I would only hold bitcoins and maybe Litecoin.
Bitcoin is every one choice and its would be great in the future. BNB is good coin and have potential in the future. Tron have good team and the company strategy very good and i will hold TRX for long term
