Everyone was making such a big deal about Google, and BOOKFACE banning the advertising of ICOs. Who really cares, that will probably be better for the cyrpto world anyway. Taking out the scams will make a healthier market, and will give it more legitimacy if people are not buying these crap coins, and getting scammed. But Amazon could actually have a huge bump for them, by accepting them as a payment, but we will wait to see if that happens. Especially with their new partnership with Visa I believe. But what was the motive of Google and Facebook's move? Was it a move of self-preservation? They have never really been challenged as a market leaders, and in many aspects have a monopoly that they are trying to protect.
I think the latest down turn has more to do with the Tax man, and the fact that the IRS is going to make this a point of focus. Coupled with the fact that Coinbase was forced to become a Narc and send out all the info on its accounts since 2015, probably has a lot of people worried, and they are getting cash on had. No one wants to become the next Wesley Snipes.
