Bithumb placed BLAST on its trading caution list on Oct. 3 and suspended BLAST deposits from 1:30 that day. The exchange said BLAST Foundation’s plan to end mainnet operations requires further review of the project’s business continuity, actual progress, and potential effects on the token’s use, purpose and functions. Bithumb will announce between Oct. 12 and Oct. 16 whether it will remove the caution designation or terminate trading support.
