The highly anticipated ETH futures go live Monday February 8th. A word of caution, however Brief look back at history.
December 2017, BTC was at an ATH. CME futures went live December the 10th. By December 17th BTC and the overall market started its descent into 2018 until the market became relatively flat.
Billions exited the entire market, rumors of nationwide bans surfaced, coins, and tokens died by the thousands as their resources dried up. Scams were prominent, arrests and charges followed in many cases.
It was no singular action or event IMO that caused this, but the rumors come from dark corners of the world. These markets are manipulatable just like any other asset market. So history often rhymes as they say. Once futures go live beware of toxic rumors and other news that begins to come out.
BTC's run may have also topped at this point as well, which is worth noting.
