Wonder about the impact of the new trade-ups? There are ~20 million coverts (excluding knives and gloves). Even if you traded up every single lower-tier skin to a covert, it only adds ~9M more. In the worst-case scenario, if all ~29M of those Coverts were traded up, it would roughly double the supply of Knives & Gloves from ~5.5m to ~11m. However, that would require every single skin to be traded to a Knife/Glove. It is more likely that the total supply increases far less.
