Hey OP, just wanted to add here more mempool viewers and fee estimators

1. https://btc.bitaps.com/ (under the mempool analytics section)
2. https://www.buybitcoinworldwide.com/fee-calculator
3. https://www.blockin.com/stats/unconfirmed-txs
4. https://bitcoiner.live/
5. https://btc-fee.net/
6. https://spookiestevie.com/bitcoin/
7. https://bitcoinfees.net/

please remove this site or add a warning about it.

It you scroll to the bottom of that page, you can see that they are basing that recommendation on data from block 631174, which is over 2 weeks old. Trying to use the "refresh" button to fetch newer data also does nothing. Not entirely clear why it isn't updating like it should, but in the meantime, nobody should use or recommend it since the mempool is essentially emptying with each block and 191 sats/byte is a massive overpayment.
