Bitcoin will have the reputation linked to Ponzi schemes and we will be tainted being associated with MMM.
I think the price crash from $500 in november was mainly caused because of the MMM coins being dumped, so I'm not really worried about this. But if..... If these coins haven't been dumped yet, then yes, we can expect the price to tank even more.
I can't see the MMM Ponzi coins being a problem,most of those coins would have been cashed now, the collapse only means there are no funds left
Unfortunately,Bitcoin and Ponzi are linked the same as with terror, guns,drugs etc but no more than fiat is,it's just the media making fud that sticks
Plus plenty of scam coins,ICO crap being released like diarrhea,that doesn't help
Honest Devs would welcome a bit of regulation to get taken seriously by average Joe
