There are always 2 sides:

One side are "serious firm" owned by quite big exchange:

"This casts a different light on Ivanov’s allegations of a “FUD campaign” organized by Alameda Research, a sister company of the FTX exchange. Even taken at face value, a public short campaign by a firm as serious as Alameda would be a sell signal to any sane trader, and not mere “fear, uncertainty and doubt.”"

Other side are "serious devs" of particuler coin:

"0xHamz also made the far more serious allegation, based on blockchain data, that Ivanov personally moved a massive $300 million pile of WAVES tokens to Binance, saying the move “could be an imminent dump.” In a Twitter Space organized by Waves on April 5, 0xHamz was invited to discuss his allegations directly with Ivanov."

Where is the truth only "serious markets" know.

Before you make your decision you should seriously consider all the above cites and below article link, and buy at  the price as low as possible, and sell at the price as high as possible too.
