There are so many exponents to the speculative equation that sometimes I think some of the risks have to be ignored. I personally am new to trading cryptos I've sat on sideline trying to calculate risk for too long only to eventually get some skin in the game. some of the issues keeping me on the fence are like you said possible bubble (risk are risk so I understand this one) scams and new laws we are right around the corner from a possible net neutrality repeal that could greatly hurt the market creating hardships for traders and potentially setting a class structure to the internet.
