Looking at the market value of Burst in coinmarketcap.com, its in a pathetic market value of only $90,378,679. Thats under $100,000,000! This is a good display of either how inefficient this market is, or how inefficient the flow of information is.
It's probably partially because of bitcoin dropping in value since its ATH. Investors get scared when bitcoin drops. When it starts rising again they will buy back into burst (and take a haircut from selling low then buying high).
