Vechain is far more reliable than many altcoins today simply because they never stop to deliver, in future vechain will be as good as NEO for trading and long term holding, any alt that's very good at withstanding bad market are far more reliable
And if you are a holder of this coin, you should just keep yourself updated to their developments. Because that will give you hints on what direction they are heading. And I think, that is true to other alts that you want to explore with. If you are a holder, you need to keep up with their updates, otherwise, you may be left out. And some of them will go down without your knowledge, and you will be a bag holder of worthless coins. So it is important if you are a holder of specific coin/s to know what is going on with the project so you can decide whether to continue holding or not.
