We just never know what is going on when it comes to this kind of stuff. However, as this gets bigger and better known, and as news of what Sphere is up to starts leaking out, I am sure we will pick up all kinds of nefarious activity including manipulation, those who spread FUD, various short activity, bashers, pumpers..... it always happens.
What we do have going for us are the facts (many via HTFBS research), a small float, and an even smaller active float that gets smaller by the week. Those on the inside of this who know the potential of Sphere's disruptive technology (including management), don't care one bit about a dollar or two up or down at this point. They have their eye on a much bigger prize. Just put this one away for now and don't worry about the hourly/daily/weekly fluctuations. The fewer weak hands we have, the less effect the manipulators will have, and they will eventually go away.
