Most likely, such a dump of this project happened because in a few days they have to give out rewards for the bounty campaign. Perhaps this is an artificial price reduction
Is it true? as far as i know if the first batch of DIA data will be distributed started from the 18th of this month. It looks like that's not the problem as the bounty token is not yet getting distributed to the bounty participants. When dia has already listed on binance and that has become the main consideration to holders to sell their tokens and go for another project.
Almost the entire cryptocurrency market has shown a sharp decline in prices over the past few days and therefore I also see no reason to believe that the drop in Dia was due to the upcoming distribution of rewards for the Bounty company.
