There is one controversial Blockseer Bitcoin Mining Pool that is started to censor transactions from blacklisted wallets.
This pool also requires all miners to pass KYC procedure!
Blockseer is first North America bitcoin mining pool that will meet all US Government compliance.
They are located in San Francisco and have parent company DMG located in Canada.
This is alert for everyone, and we should not allow this to spill over on other pools.
