Every idea is vaporware at some point, it's not like we can think of something and magically it appears.
I agree, but you don't go on stage and start selling your idea before it's implemented.
We aren't talking about shares in a company here, we are talking about currency.
1) idea
2) write & code
3) peer review & test
4) implement
5) tell people about it
Don't start telling people about your idea (and try to get them to buy/pump your coin) before even releasing a paper.
I understand your frustration with things like this, but like all businesses and companies I've been around they all blab their idea's and then try to make them into reality. It's very hard to follow through with any idea, I struggle with my business daily. But it doesn't mean it won't happen.
To give an example, we can look at the USA presidential debates, they all promise things and basically give no supporting evidence it can be done. But something comes out for better or worse.
There are winners and losers in every race, in every business.
the thing with a cryptocurrency is:
if you are selling it before testing the security and something goes wrong, a lot of people will loose money...
So start selling it after testing, that is the logical sequence.
edit: yeah, I know, businesses can fail also...
But cryptocurrencies can at least be tested and reviewed before launching it (or launching new features)
I get it, I really do, but I think all crypto is failing us in this aspect. They all present amazing stuff and most of it is junk, but got to have faith sometimes. So invest wisely.
