Live snapshot of the Bitcoin mempool: number of unconfirmed transactions, total pending virtual size (bytes and MB), the current backlog in blocks, total fees pending (sats and BTC), the fee-rate histogram, and the current chain tip height. Lets an agent gauge network congestion and time a transaction.

Live recommended Bitcoin transaction fee rates (in sat/vB) for next-block, ~30-minute, ~1-hour, economy and minimum confirmation targets, straight from the mempool. Also estimates the total fee (in sats and BTC) for a transaction of the given virtual size, so an agent can pick a fee tier and know the cost before broadcasting.

Impact if the top holder and top 3 exit; verdict resilient → exit_trap. USD stablecoins: not_applicable (see stablecoin-peg). Heuristic; not financial advice.
