Earlier this year Crypto.com announced they were unburning 70B CRO (increasing supply 233%) so they could raise funds by directly selling CRO to third parties. When CDC sells it doesn't impact market price but when these third parties decide to sell - it

Crypto.com selling brand new minted CRO does not impact price, it is just Crypto.com raising money on freshly minted CRO. But when those third parties decide to sell the CRO they bought from CDC it will dump the price. CDC is devaluing CRO and decreasing the value of CRO for all holders with the unburn of 70B CRO. (increasing supply 233%)

Also yes they unburned CRO - they said it was burned forever then brought it back against the will of all cro holders.
