 Stone door says does the conventional wisdom of dollar cost averaging and don't reuse addresses need to change people with many small UTXO seems screwed as fees increase Stone so glad you asked that because this is a very very critical issue that has gone unnoticed by many and is not being discussed and As you say the conventional wisdom has misled a lot of people into making this mistake So dollar cost averaging means that it's best to buy your Bitcoin At regular time intervals regardless of price so rather than putting in a lump sum of whatever you have now Putting in a bit at a time say investing every Monday afternoon regardless of what the price is doing will give you a better on average price The dollar cost average meaning your cost basis in dollars for the acquisition of that asset And it's a technique the traders use in many many different assets Not reusing addresses has more to do with privacy and security Than anything else, but often people combine these two things The problem comes when people don't understand the next important step Which is just because you bought the Bitcoin every Monday doesn't mean you also withdraw it immediately So the problem isn't combining DCA and don't reuse addresses. The problem is combining very small amounts DCA and address reuse advice with my advice of not your keys not your coins Don't leave money on exchanges and instead what you do is you buy every Monday and then withdraw every Monday and Honestly, it doesn't matter if you withdraw to the same address or not Because the problem of UTXO exists whether they're in the same address or not It doesn't really matter each withdrawal will be At least one possibly more, but hopefully just one UTXO and if you're withdrawing every money that every Monday the tiny amount that you just DCA'd You're gonna pay a fee for that withdrawal But then you're also going to end up with a pretty small UTXO sitting in your address same address different address Doesn't matter. You still have a small UTXO and so You end up with this Fragmentation you end up accumulating dust and then when you try to spend that you're like, oh great. I have a thousand dollars in my account Yes, but what you don't realize is that you don't have a thousand dollars. You have ten thousand Ten cent UTXO's and to spend ten thousand ten cent UTXO's you need to make a transaction with ten thousand inputs And that transaction is going to be a jumbo transaction a whopper of a transaction and the fees on that are going to be huge And you're gonna end up chewing up a significant percentage of your investment in paying for those fees So how do you we tweak this advice in a practical sense, right? Because that doesn't mean stop dollar cost averaging and it doesn't mean leave all your money on a on an exchange It's mean understanding the technical nuance and applying it correctly and The way I would do it and in fact the way I did do it is If on dollar cost averaging small amounts not in the hundreds or thousands of dollars And I don't want to have UTXO's that are small you know under I would say anything under $500 in the current price Environment in Bitcoin is a small UTXO So if I don't want to have UTXO is that small What would I do? Well, I can dollar cost average every Monday But only withdrawal once the amounts that I have on the exchange is at a Level the balance that I have is big enough Then when I withdraw that is sent to me as a single UTXO of the total amount that I've told across that I've still dollar cost average my cost basis is still the every Monday price on average You know average down to over how many average however many Mondays I've been doing this So I've achieved the dollar cost average goal, which is to to smooth out rapid price fluctuations and volatility and Get a good cost in dollars on average for your Bitcoin So I've achieved all a cost average and and if I withdraw once my amount exceeds my balance on the exchange exceeds $500 a thousand dollars something like that Whatever the number is for you the number that you wouldn't cry if you saw it disappear But we'd also not create a UHTXO. That's too small And incurred too large fees. Well, then I withdraw so you have to find that balance What is the balance for you whether UTXO is not small enough to chew up everything and fees and But it's not so big in balance terms that if the exchange gets hacked you're going to be Losing all your savings, right? And so DCA and don't reuse addresses are still good advice and and the not your keys Not your coins don't leave money on exchanges is still good advice, but No advice is perfect for all circumstances and just because you have advice doesn't mean you take the maximal position of each Statement and then combine them all to create the maximally Best scenario that's that's not how life works, right? There's nuance here and there's technical details You need to understand so if you take DCA to the extreme and you take Don't leave money on the exchanges extreme and you take don't reuse addresses the extreme You end up with a very messy wallet with tiny UTXO spread a lot of addresses and very high fees Theorem and the internet of money series if you'd like to support my mission of bringing Education about Bitcoin and open blockchains to as many people as possible under open free creative commons licenses Please consider subscribing to my channel and supporting me on patreon.com slash A-A-N-T-O-N-O-P.
