The question you asked is really important and I think there are person that don't care much about privacy.The mixing tools you made mention of like whirlpool, joinmarket and wasabi are still being used by many but the most important is the method of usage or how we utilise then .despite how active and sharp Blockchain surveillance maybe, if we still know how to make use of this tool it will really help alot.So the tools you mention are very good if we know how to use them.Also I do make use of samourai, stonewall and I do avoid combining UTXOS.Infact it is important to use multiple tools.
Samourai still functions in 2025? I thought they lost and closed down? I don't hrsr about them anymore since I lost some Bitcoin using their service, I was still very new to Bitcoin at the time and I sent some Bitcoin to an address but instead this wallet sent gas fee to the wallet address and kept the $200 as the main gas fee, this was how I lost everything.
I was using Electrum too so It was not my first time sending Bitcoin, how and why they use my balance as gas fee and credited the address with small tinny Bitcoin is unexplained till this day.
I've seen news online where people use 10 BTC to send half BTC, how and why they make such mistake remains a misery for me, maybe someone can explain to me why this happened.
