There are various ways to manage UTXOs manually too, in terms of batch sending and even having several wallets that might have varying balances of bitcoin in various UTXOs, so even within a wallet there might be several accounts and within an account there may be several UTXOs, and we can manage our UTXOs with coin control.
So if I am going to buy some furniture from a store and it costs something like 0.011432973 BTC for the whole purchase and maybe I have a wallet that has an account that has several different sizes of UTXOs, so I utilize coin control to send from a wallet that has some slightly higher balance.
Or maybe I have time to pay in advance, so I end up selecting from a wallet that has .079342152, and so I decide to send 3-4 transactions simultaneously, so the recipient cannot determine which of the UTXOs are under my control and which of the UTXOs are not, yet sometimes we still might want to be careful about having transactions in the same hop, so we might want to have an extra hop in there so that, the transaction is sent from even a smaller wallet that is closer to the size of the transaction, so then the recipient sees the transaction coming from a smaller wallet. We could also use lightning network, and there are more and more tools coming available to obscure bitcoin transactions. Some folks choose to use a wallet from an exchange, which sort of defeats part of the purpose of peer to peer transaction, even though it could be useful in some cases to use exchange wallets that would not show our own personal account balances.
Not many users truly understand how much metadata they leak by just casually spending without considering UTXO structure or coin control. Your example perfectly Explains why intentional input selection matters, not just for privacy, but also for avoiding dust, minimizing change, and protecting spending patterns. The part about sending multiple transactions or routing through an intermediate wallet is a clever tactic. Many still underestimate how powerful an extra hop or even simple wallet separation can be in breaking heuristic assumptions used in chain analysis.
As Bitcoin matures, I believe privacy conscious behavior like this will be more crucial, especially with increasing surveillance and blacklisting on chain. Tools like the Lightning Network and even collaborative coin joins like Whirlpool or JoinMarket also deserve more adoption among users who care about fungibility....
There can be situations when people end up sharing too much, and even if I do a bitcoin transaction with a friend in 2017, yet if I do not move the change address, the transaction in 2017 might have been worth a couple thousand dollars (1 or 2 bitcoin) and maybe my change was a couple thousand dollars (1 or 2 bitcoin), but then that balance of 1 or 2 bitcoin is now worth way more than what it was worth in 2017, and many folks do not even have 1 or 2 bitcoin, even though prior to 2017, we might have had been transacting with several bitcoin at at time, especially if we might have made some large purchases with bitcoin, we may have sent several bitcoin for a transaction that was a couple thousand dollars.
This really highlights how drastically Bitcoin’s value has evolved over time. What used to feel like casual transactions like sending 1 or 2 BTC for basic purchases now seem like moves worth a small fortune. It’s crazy to think that something as simple as not moving your change from a 2017 transaction could mean you are still sitting on a huge balance today without realizing it....This is why Bitcoin truly rewards time and patience and why being cautious with past addresses and transaction history is more important than ever.
This cycle is the beginning for some, and so yeah, anyone new to bitcoin likely will need to spend a whole cycle or a few cycles building up his bitcoin stash, and it tends to take a decent amount of time to build a bitcoin stash, even if a person is relatively focused on accumulating bitcoin.
Many people underestimate the time and consistency it actually takes to build a meaningful Bitcoin position. It is not just about catching the perfect dip or riding one bull cycle, it is about developing the mindset to accumulate steadily, even when the hype dies down. Every cycle teaches something new, and those who stay committed through the quiet phases are usually the ones who end up with the strongest hands and the biggest rewards in the long run. This current cycle could be the proving ground for a lot of new entrants.....
