The mere fact that you refer to them as cryptocoins tells me that you're ready to start giving sound market analysis.

I say "cryptocoins" rather than "bitcoin" because bitcoin is obviously only one of them, and any of them would serve for that otiginal goal.
-you don't own any "cryptocoins"
One excuse for that is that it helps me keep neutral. Fom watching the bitcoin scene, I now strongly suspect that if I owned even
one bitcon, I would start looking for "bullish" facts and thoughts and ignoring "bearish" ones, would prefer models that show its price going up, would wish for more people to invest in it, would wish for the other altcoins to fail, ....
Do you really expect a different reaction from us? I have no problem with people giving honest criticisms to cryptocurrencies, but this is obviously not the forum in which to be doing it. I would think the developer forum would be more to your intellectual liking. Traders here are generally aware of how they work, inside and out, are aware of the risks, and have heard it all a hundred times before.
I know that this is not the place to criticize bitcoin, and I try to avoid proselitizing. But I have been criticized (to put it mildly) for "hiding" my negative feelings. On the other hand, if someone posts claims about bitcoin that I believe are incorrect, why can't I reply?
As for the reactions, I don't mind people blasting my ideas. To those who take it on my person instead, I warn again, don't push it -- you don't know what I am capable of (both in the sense of "having the means" and "having no mercy".) Anonimity, distance, firearms, friends in the Yakuza, tears from you mom -- nothing will protect you.
