According to Bibox announcement, Bibox was suspended SDS trading on 4th April 8:00PM (GMT+8).
The reason Bibox suspended SDS trading was due to lack of trading activity, Alchemint is proactively communicating with Bibox to make corrections, and trying to resume trading as soon as possible. Please follow Bibox and Alchemint updates regarding resume trading.
During this time, you can leave your SDS in Bibox exchange’s wallet, but we always recommend people store cryptocurrencies in their own wallet.
For now, we suggest trading SDUSD and SDS on https://switcheo.exchange
We sincerely apologize for the inconvenience.
