The more various opinions I hear about Cryptocurrency, the more I realize that there is a new kind of phobic hysteria, which appears literally about everything related to Cryptocurrency, e.g. mining, trading, ICOs or lending.
It's not phobia in my opinion. It is more like scared to get in to an unknown world. Since Bitcoin and other cryptocurrency is very new to others and the price swings are volatile especially now that Bitcpin's price surged up (which we should handle with skepticism) is getting all in their mind that this is very different from what they have known in traditional monetary system and even in stocks. Just give them time and mke them understand.
