There is no explanation on the buy wall except AMP team manipulation. This is what happened we weeks ago as well untill it all collapsed back to 6k where it belongs lol.
edit. end pooof fake buy wall is gone

Its the same fake pump like team did just before ico.
There where lots of 10 to 25 btc buys but the price was barely moving , its all fake.
How do you know that it's all fake? Have you even used the Alpha?
The FUDders are making a huge mistake, news of this platform will spread. Why? Synereo has a Google Chrome extension that will allow anyone to make money by sharing good content - it only takes 3 seconds to use it. Some people are going to try to get rich off of the system by leveraging their AMPs and promoting YouTube videos. Naturally, their friends and acquaintances are going to find out and will want a piece of the pie - and so it will continue.
