[3] Sure, np. Let me clear up the possible but not absolute blockchain connection for you, too.
Yes, that last address, either belongs to
my exchange,
p2p trader, or
gambling website (I don't have access to that wallet info anymore, given the amount of time elapsed)
This is how, I trade off-forum:
I've exchanged multiple times and gambled money in different casinos depending on the speed of the network (Now I mostly prefer BNB trades and loans, and yes, I take loans off-forum, even now).
So yes, there is quick transaction time between trades when trades occur through DM, within seconds to minutes.
People are active; you don't have to wait hours like on the forum for someone to read your post, look at your profile, and then provide a loan or trade; it's very quick. BTC isn't the only currency I trade with, and SF isn't the only person I've traded with.

bc1qcvdfnn0c06dewqtexjlev9z4nspwku5kat4wd9", and "
bc1qc240qa82qergkzzwpasg8ehp0clzt6gkzznwhc" (Also belong to me
most likely).
The later address "3EUhPUmdDcck8MeGSoBoPzRVSjDAZVdh68" (I don't know of which site is, but it most likely belong to account, or someone other than SF I traded with or had a deal with, I deal with a lot of people so I don't know who that might be, I could've provided logs if the person if from a p2p exchange, or a trade through dm but it would consume unnecessary time, and cannot guarantee I will find that person).
The transactions made to "3EUhPUmdDcck8MeGSoBoPzRVSjDAZVdh68", from both addresses above, are through unconfirmed inputs from addresses of same wallet (most likely) (I could've preferred to wait, and send them separately) or I could've given sf that direct address "3EUhPUmdDcck8MeGSoBoPzRVSjDAZVdh68" to send the funds to, but I wanted to do it through my address (considering there, if any verification takes place, for the trade I did with 'h68' address, I can cite my owned address which send funds to it, I do it mostly with everyone, I trade occasionally.
