Bio Protocol transferred 80 million BIO tokens valued at $5.15 million to Binance and OKX after the token climbed 100% over two days, according to on-chain analyst Ember. The movement occurred about eight hours after the project introduced BIO staking (locking tokens to earn rewards) for token sales. Transfers to major exchanges can draw market attention because they may signal preparation for trading activity, although the source only confirms the token movement and timing around the staking launch.
