But today, I've got it too much. I've posted a comment which was very quickly downvoted and then flagged:

In this comment, I gave a link to interview hosted by YCombinator:

https://blog.ycombinator.com/blockchain-investing-with-olaf-carlson-wee-and-aaron-harris/

In this interview Olaf Carlson-Wee, a founder of Polychain Capital, discussed MakerDAO, a decentralized stablecoin. I mentioned MakerDAO in context of controversy aroung Tether. Namely, I suggested that decentralized stablecoin could be alternative.

I've not just mentioned that I feel very enthusiastic about decentralized stablecoins. I also mentioned concerns about their viability. For example, British Pound crash during Black Wednesday of 1992.

Hacker News readers implicitly told me today - you are scammer and you advertise yet another pump-and-dump scheme.

In other comments I suggested that ICOs are not always scam. A good example is Tezos. A perfectly valid project with good intentions despite all legal controversy around it. It was also mentioned in interview with Olaf.

It should be still possible to protect retail investors from scammers without barring them from such early-stage investments. One of my ideas was to have some government approved platform where projects should pass some due diligence before fundraising.

I've got swiftly downvoted every time I mentioned that.

I'm aware that we are currently in a big cryptocurrency bubble. There are lots of questionable projects and outright scam. I would say that 90% of cryptocurrencies and ICOs are junk.

If most of HN readers share views of Roubini who call cryptocurrencies as "Mother of All Scams", then I'm out of HN.
