Aevo Trades Billions of Dollars in Volume, Then Plummets, Sparking False Trading Allegations Some market participants have claimed that Aevo's trading volume has recently been inflated by wash trades. When asked about these allegations, Aevo said that the increase in volume could be related to "airdrops". Wash trades, in which the same person acts as both buyer and seller in a trade to create a false sense of activity, are prohibited in traditional markets such as equities.
