According to VISOR’s official announcements, the Visor project merged with Gamma after an exploit to its staking contract; and VISR tokens are migrated to GAMMA with an airdrop where VISR addresses would be distributed with GAMMA tokens at the ratio of 1:1. Gate.io supports the airdrop and has distributed GAMMA tokens based on users VISR holdings. Gate.io users can now check the GAMMA tokens received on My Billing Details page. According to the Visor team (now Gamma team), the VISR tokens have nothing to do with their team any longer after the merger and airdrop, and they don’t support the trading of VISR any longer. There may be some decentralized exchanges where VISR is till trading on, but users should take cautions and beware of the risks.
