Your first concern I would like to say that there will be alot of other ppl that wont be in panic mode like me and I would keep buying it. I truly kinda think that they are already manipulating it with cash but it dosent work to well for them because when the fed starts selling alot of bitcoin to bring the price down alot of people buy it back up and then the fed has to buy at a higher price after that so but at the same time they can keep printing money so for them it might not care for them to much but we'll see but for the most part hold bitcoin and see where it takes you I think its going far its already proving that it can do that from what its done already.
