It might be more constructive to answer the criticisms rather than attacking those raising them.

You seem to be placing a lot of your own emotional baggage onto other people's concerns. Most people talking about Bitcoin and similar just aren't that vested into it (either literally or figuratively). For example this:

> since bitcoin was $1 and missed out on the rise. So now they are actively rooting for it and all cryptos to fail, and ignore the benefits of the blockchain.

The fact you perceive anyone critical of Bitcoin and similar blockchain currencies as jealous is very much deflecting your own baggage.
