Signs of possible price manipulation have emerged in at least four tokens — SIREN, AKE, XPIN and BTR — after each rose more than 10-fold, on-chain analyst EmberCN said on X. The analyst linked the moves to a specific market maker described as recently highly active and highlighted AKE as a notable case: its price was pushed down by about 60% in early July, then climbed roughly 52 times within a month from $0.00019 to $0.01. EmberCN also said one address involved in AKE trading matched an address previously used in the alleged SIREN manipulation and was used again today to transfer XPIN to Binance Alpha.
