This your talk is somehow, because i don't know if you are against bitcoin or if you are for bitcoin, but if you are against bitcoin that is your choice, because when it comes to investment everybody will make their choice for themselves on what to invest in.
So what are my saying investing in bitcoin it's not compulsory, if you don't want to invest in bitcoin you can invest in something else and  allow us who are investing in bitcoin to be. Yes bitcoin is risky with high return only if you can take the risk by buying and holding for long term and not trading it.
