Yes, crypto currency is still closer to 'gambling' than to 'investment' so there is more emotional energy involved in those who are genuinely promoting it as a long-term investment. Especially when those who are in the early waves of a developing idea/technology tend to be young and lie in the range between activists and true believers. They tend to get upset that someone who has already been through the 'cult' phases in their youth question the 'rose colored glasses' narrative in any manner.
I was quite specific in mentioning that I had, in fact, chosen PIVX as a good long-term investment to stabilize a portfolio as cryptocurrency transitions away from the 'gambling' to a true 'investment,' yet I still got a lot of flak for asking the kind of questions that you should be asking before you dive into something.
Of course, when social forums are run by volunteers/activists rather than by pad staff, it is inevitable that you will end up having to deal with some of the problems that arrive when youth and inexperience are being fueled by hormones. Hard to bitch too much when you're not paying someone to cater to your needs. Unless you're an old grouch...
