Most of the people who seriously believe a coin has long term value will probably keep quiet, because they're still busy investing in it and don't want anyone else to push up the price. Always good to read between the lines of what people aren't saying, as well as what they are.
I disagree. In fact, I think there are no good long term crypt coins on the market (possibly BTC). But, there will be a better future-proofed coin made in the next couple years..
We're all investing in the medium term here.
