I am going to devolve even further... Might be a stretch, but if you are not using a VPN, and you are searching BTC addresses, and you search a bunch together, might there not be a presumption that the person who searched those BTC addresses is the owner of the addresses? Yes, I am maybe overly paranoid.. but there can be some difficulties in knowing how much privacy we might have if we are not covering up some of our traffic.
^This can not be emphasized enough.
I believe it was in this honourable WO thread some time ago when somebody hinted at running Electrum against public servers (especially for i.e. watch-only cold wallets, or other wallets with more than dust in it) to be a huge opsec risk. It made me switch all my electrum wallets to using my tor proxy in the next minute after I thought a moment about it.
De-anonymizing a dynamic ISP IP or a VPN IP is not as difficult as one might expect and if there is a known, nice reward for wielding the wrench, the motivation for wannabe and professional wrench-wielders could be very high at a minimal risk (minimal compared to other kind of "forced wealth transfers" these sort of people might be specialized in).
For me, my next step - motivated especially by some recent encouraging posts here - will be running a full node, my own electrum server and I also want get some hands-on with LN but I have not the needed resources for that kind of setup yet.
