My stress-free method of doing that is buying/selling at fixed days, either monthly or weekly.

Yes.

I've learned a long time ago that I can't time the market.

Yes, it happens. But it happens in the other direction too.

Sure you can. If Bitcoin goes up, you could have had more by buying sooner^*. If it goes down, your purchasing power goes down.

That's what matters. If it works for you, keep doing it

^* Hypothetical, of course. The same "problem" exists if you spend Bitcoin, and it increases in value afterwards. But as I read on the Wall Observer a while ago: "That's the problem we want to have".

I hadn't realized this until you posted it. It makes sense, and they don't even need the mempool anymore, all they need to check is every new transaction the moment it first arrives. So that's at most 7-ish transactions per second, or better: every xxx milliseconds a new transaction arrives, and they check them instantly (one at a time).
Kinda like BitBonkers, but with sweeping instead of visualizing.

But why? What's the point of making 204 small buys instead of just buying $500 worth of Bitcoin at once?
DCA is only worth it if the price drops. In that case, you'll end up with more Bitcoin. But if the price goes up, you would have been better off buying in a lump sum. And even if you buy $500 "lump sum", it's still considered DCA if you do it every month.
Because Bitcoin goes up on average (why else would you invest in it), I believe your DCA-method will result in a (slightly) smaller Bitcoin stash than if you'd buy $500 worth of Bitcoin once a month.

First, you should realize "safe" is always a compromise: it's never 100.00000000% safe, there's always some risk. So that leaves the question if it's safe enough, and the answer depends on your personal preference.
I connect my smartphone, laptop and other devices in the house to my router. Many people do that, and it's not something I worry about. At least the router uses NAT, so that's an additional barrier between the outside world and my device. I'm not sure if my mobile data provider does that too.
The next later of security is only using small amounts in your hot wallet: don't keep all your Bitcoins on your phone! Use offline cold storage for the majority of your funds, and only expose funds that you can afford to lose to the internet.

Yes, it happened to alia too. I expected this one to be fast.

For me, that would mean manually editing many files. I don't really feel like doing that, once something's on the internet, it can't be forgotten anyway. I've updated my complete List of all Bitcointalk usernames.

That means nothing. It has always been obvious to find which transactions (likely) came out of ChipMixer. Adding an arbitrary "risk" score is just a way to make you believe your Bitcoins are somehow worth less than someone else's Bitcoins.
The solution is easy: don't use any service that claims some Bitcoins are "tainted".  Money is fungible, treating Bitcoin as if it's not is an attack on the very existence of Bitcoin.

I'm not sure. I guess it's some customized wallet software.

See for instance Collection of 18.509 found and used Brainwallets, but it could just as well be from hacks or leaks.

Clams aren't worth much anymore. And I'm pretty sure someone thought of claiming them already

Good point. They're probably being sold already.

That's not going to be easy without manual checks. Many people post keys knowing they're compromised already, or they're partial private keys for (secure) vanity address generation. Many keys gets posted more than once (or quoted), and I don't really want to check 10k+ posts.

No, that can't happen. Just one bot is enough to take the money, and if nobody runs it, someone will. If it's profitable for one person, someone else will do the same. So even if some people stop their bots, others will join.
It's never going to change: once a private key is compromised, funds will disappear.

Not all transactions are dust.

I once entered my private key in a Google search field. It's such a common thing to do: "CTRL-V > Enter", and it's gone. The best way to prevent this is by making sure you can't make this mistake: never handle private keys on a system that's connected to the internet.

I was curious about that scenario too. That would mean that (eventually) only miners profit from funds sent to addresses with leaked private keys.

Did you click the first 2 words of this topic?

My list is indeed not complete. I didn't search for Hex keys either, only WIF.

I didn't search for altcoin private keys.

That must be why the wallet grew to 2.2 GB. With just private keys, it was only a few MB.

This post made me curious: how many private keys have been posted on Bitcointalk?
To find out, I searched all downloaded posts (which took hours) for anything that could be a Bitcoin private key. That resulted in 9375 potential keys (not all of them are valid, and no, I won't post the list).
Yesterday, I imported the private keys into a new Bitcoin Core wallet (this took only a few minutes), and did a rescan. This took forever, but was mesmerizing to watch: the balance went up and down by many Bitcoins, and this kept going for hours! I left it to finish overnight.
This morning, Bitcoin Core was hanging. I killed it, restarted it, and it took forever to load the wallet (which had grown to 2.2 GB during the rescan). Eventually, it worked! It's up to date, and the total balance is 0 (as expected). Every few minutes, Bitcoin Core is unresponsive for a few minutes, most likely because of the large wallet combined with a lack of processing power. It's not very nice to work with, and consumes 1 full CPU core.

Scrolling through the transactions, it's obvious any incoming transaction instantly gets sweeped, usually at a high fee. I assume many people have systems monitoring all compromised private keys, and they're competing against each other to steal the funds before someone else does. Back in the days, it happened to large amounts of Bitcoins, but the more recent transactions are mostly small. Except for last month (January 24): this address received 0.84362383BTC, which was instantly sweeped. The private key was posted 2 months earlier:
Someone made a very expensive mistake funding it. I'm hoping pbies can tell me where the private key comes from.

TL;DR
Don't post your private keys! Don't post your seed phrases! Don't try to be smart by creating a brain wallet!

No spam
Self-moderated against spam. Discussion is of course allowed.

From what I've seen, Admin can be faster when it's for privacy reasons. But even if OP's name gets changed, his name can always be found back later. Once it's on the internet, it can't be forgotten.

That would really break the link with OP's current account.

I don't get why altcoin giveaways aren't allowed, and this bounty crap is. It looks like a gigantic loophole to this:

How is this not a violation of theymos' rule?
Let's see what's posted:
On the first line, he can't even type the correct word.
The second line posts his username. Yes, we can see that already, and offering to pay people to post their username was specifically mentioned by theymos.
The third line posts a link to his profile. Yes, we can see that too.
Then the ones they're going to spam: Telegram and Twitter, apparently.
The last line shows an altcoin address, that's also what theymos mentioned, and by my interpretation isn't allowed.

This whole post is utterly useless. And there are millions of them!

Bloom filter Newbie here: what can this be used for?

I'm no expert on copyright, but I've seen enough to know this is not how it works. It sounds like you're using commercial software as if it's GPL software. That's now how it works. Even if your claim is true, 40% is copyrighted by someone else. And the fact that you based the other 60% on their work isn't allowed either.

Of course it's easier, but that doesn't make it okay.
Why don't you start from scratch? That way you can really call it your own.

He should read this:

Are you using a hot wallet for long-term holding?
