Probably it's not supporting Bitcoin or Ethereum anymore and only supporting Binance Coin because Coinmarketcap is owned by Binance...
I think it's safe to say they were using the other cryptocurrencies to draw more attention or rather traffic to their explorer...
- I just noticed that the "onion link of Blockstream" is the same as the V2 address of "Deep web explorers" and since it's no longer supported, I think we should remove them as well.
I've removed it and deleted the entry:
It seems that you "
forgot to remove the latter part" that also uses the same link

Many thanks for your updates.
You're very welcome and thank you as well for updating the table.
