I tried to open OXT and search an address, but it doesn't work (Address / tx isn't loading, tried for several browsers. I'll try tomorrow again) Maybe someone else also can't load it
)
Uhm... it works fine on my side... Maybe it didn't work on your side due to a maintenance of the website (which was completed meanwhile)...
Later Edit: I would like to propose now
https://bitcoinwhoswho.com. This one isn't mentioned in OP and it has very interesting features
Added. At first, where it didn't seem very user friendly, I was a bit disappointed but it seems to be an interesting tool. I won't call it explorer *
(I've just taken a random address posted on the site flagged as "scammer address"):
Scam alerts are added (I don't know how such reports are determined)
Yep, this tool is awesome due to this feature of flagging scams. Regarding
how to create a flag, on the upper side of the website there is a button named "Report Scam". If you click on it, a new page is displayed, where you can insert the BTC address involved in a scam, but not just that. And here things become very interesting. Excepting scams, you can also report "Bitcoin Abuse, Scams, Blackmail and Extortion Emails". Besides, the reporting page also offers a link for making a report directly to FBI
*But we can't view transactions, only Bitcoin addresses can be viewed.
Yes, I observed that now... But you can see though all transactions performed by any address.
Excepting all these, I'd also like to mention that I
updated the Romanian translation of the topic with three new websites added by you in OP: mempool and CoinCap - sugested by SFR10; and BitcoinWho'sWho - suggested by me.
