The Ether (ETH) will oscillate in the range of 3100 to 3500 for a period of time, and the purpose of this oscillation is to get retail investors to bet on whether it will rise or fall. The main players have oscillated below 2800 for several months to pump the price. The cost-effectiveness of shorting is high, as a decline can result in several points within a few minutes, but when going long, the rise generally takes longer and most people cannot hold on.
