Who are the players you launch with? Some known PROs?

Here one must be careful. IT MIGHT not be a scam as sometimes, to trick google from shutting down ads, exchanges use such third party domains for ads. Now i would never register there, but its known to happen.
This is for many businesses the only way to advertise in serach results as they create non crypto heavy landing pages where certain buzzwords are missing

Coinbase & Binance for example


What is a Mixer address? mixers use each address 1 time as far as I know and have seen. I don't see how this is still applicable in 2021. It might have been in the past.

.

Same goes for coinjoin. In the past wasabi used to out themselves by resusing some of the change addresses but now, all there is left is to label a tx as a potential coinjoin. there is no certainty (as with all heuristic approaches). The bouncing is very easy to track in any graphical display of your transaction history.



This is a good point. So as I see, randomized outputvalues with delayed payouts. How can chainanalysis or other analytical services still claim that certain TX is from a mixer. I just don't see how but maybe someone can reassure that it still works.

Overall, my question is really just that: Can one rely on this information by analytical services or not. "Known wallet" stuff is no longer applicable as from what I have seen how mixers work in 2021. Hence in the title "2021". I know it was much easier years ago.

How can Chainanalysis tell that this is not a "legit" transaction but a mixing service.

I am wondering, whether what I read online makes much sense in regards to exchanges "banning" mixing services.
I tried it and it seems not. I have tried to mix very small amounts through various mixers and used an account on a major exchange to see wheter they will have a problem with it (as they claim) or not.
Fact is no issues after weeks.

I wonder if in 2021, with the level the mixers have reached with delayed payouts etc., it is still possible to detect wheter a UTXO has been created by a mixing transaction or not.

I have no interest in mixing coins but care for analytical reasons only. I (maybe someone does) would not know what heuristic approach would be working where you don't have uncertainty to an extent where it makes no sense to call it information.

Do you happen to know (even if just testnet) examples of such opening and closing/settle transactions?
Isn't there any special bitcoin script placed in those transactions? So its a simple 2of2 output?

I have been trying to find more details about "how lightning channels" are opened but I wasn't able to find much.
The question is only related to the bitcoin blockchain and not layer2 transactions once the channels are opened. So what does a transaction do, in order to open and close a channel and how can they be distinguished from other transactions if this is even possible.

As far as I know, you need to

a) open a channel
b) close a channel (if you wish so)

Those transactions are done ON CHAIN and I wonder if there is examples that someone could/would share.

I actually did go through all the transactions with an own blockchain parser i have created (this is why i ended up asking this question) and I have found around 3500 BTC (roughly) to be sent to a non spendable output. That was just a high level rough observation, might me much more.

it was simply the difference between balances of all public keys (addresses) as of the time of running the query minus all block rewards ever issued. not sure if that is accurate enough.

thanks a lot. that is a very clear and logical answer. So indeed we will never have 21 million coins that way.

I was wondering what the Bitcoin protocol does when we reach block 2,100,000. As of now, block reward is halved every 210,000 blocks. Now this works fine so far with 8 decimal places but with block reward being 0.09765625 BTC until block 2,099,999 and its then halved, we get the value 0.048828125 which has 9 decimals. 1 too many.

So technically, really just technically, the reward isn't halved by then but either less or more?

I am just curious and fully aware that the 0.000000005 does not make any significant difference even if 1 BTC is in the millions but still.

Anyone knows what will happen? roundig? 

I would not agree more with you BUT I am not asking for if its legal, grey or something else but the economy behind it. We cannot deny the fact that there is people with over 1000+ Gift Card trades (hundreds of them) and i highly doubt, they pulled of even 10% scams as you can only scam so much with one account. So I am not asking to ENTER that market, god no! Just to understand it.

Sure there must be someone doing this business and have an insight.

Someone sending lets say 0.01 BTC for a 200 USD Gift card for example, must have a way or know exactly, how to avoid being scamed. Doing it 1000 times in 1 year. People are stupid but nobody does a stupid thing a 1000 times if it doesn't work somehow right (i hope not haha)

40% off, not 60 but yeah, same thing. I know what you mean. this is where I am but I am sure, there is a whole other business behind it bthat is not stolen cards as what I see, big users int he space do care if the card has been paid with cash and even want a picture of the receipt and that its paid with cash (removes the chargeback risk entirely). The space is too big to just be stolen cards i think

Hi,

I came here to ask a (some) question, hoping not to be fried right away as I have some legitimate questions about the entire Gift card/Crypto business...

Overall I am curious how this entire business works as a whole. I see so many offers on exchanges like paxful and even here in the forum, so I am sure somebody reading this is a pro and could help me out.
I am even willing to pay a small fee to someone who would take the time and walk me through this business on a zoom call or so (message me in pm) as I understand that knowledge is valuable.

Specific questions i have is:

1. Who are the people selling 100 USD Amazon for 60% of the value only? I mean you can get more for that on ebay.
2. How are you making sure, that gift card works and is not cancelled after you got the code?
3. Some People trade for 20k$ a day. what you do with 20k worth of gift cards a day? 
4. Are platforms like amazon allowing a person to redeem millions in gift cards a year without raising any flags?

Looking forward to understand the science behind this business model

cheers

Could you explain me about that pattern? Do you have an example of mixer with such pattern and one without so I can try it? (I assume the one in your sig is one without )

Coinjoin is rather rare but also there, how can you see its a coinjoin and not just a wallet with funds?I know that for wasabi you can check for bc1qa24tsgchvuxsaccp8vrnkfd85hrcpafg20kmjw but thats it?


This is what i find very interesting in the first place. How many txs back you go. I man if you go back 20 TX on any address, there is a fair chance to find half the bitcoins tainted in some way. The only clean BTC is a virgin one fresh from the mint, depending on how far back one goes

But why don't they use multiple addresses (like 10,000 different ones)? They actively reduce privacy on the entire network because of this.

What about mixers? How can Binance know that someone used a mixer? Of course, there is always the option of using it yourself but is that really it?

Thats what I was wondering. The moment you trade BTC with cash, the entire alerting system of your mind and body should be running on 100%. Just due to the fact that you do such a deal. Adding the amount of Cash involved, makes it even more true any even slightest flag, may it be just yellow, back away from the deal as legitimate people, NEVER give you flags.

I was wondering for some time now, how analytics software such as chain analysis or whale alert find out which wallets belong to an exchange. I was trying to find the answer but I was not fully content with what I found so I try here, where I am sure the subject matter experts can explain this to me and maybe other members of the community who care.

First, I know the easy approach of withdrawing from an exchange like Kraken and then they can obviousely see from where the funds were sent. That's easy.
That gives them in most cases 1 to N addresses that recently have been used by that exchange.

Second, they could then find all addresses ever used in combination with the ones used for the initial withdraw (as input) and like that find surely plenty of addresses and transactions that can be allocated to that particular exchange.

BUT is that enough? Is that all they do?

I doubt exchanges share their deposit addresses and withdraw addresses with those service providers even if just anonymous??

Same goes for the fact that some (e.g. Binance) started to ban deposits coming from an address that used a mixer. How would Binance know its a mixer?

If I posted this in the wrong section, I am sorry but I did not know where else to post as its kind of technical

Thanks for the many replies.

There is no payment details made public as it is very uncommon to put a payment details out in an initial post. However, the payment will be heavily depending on the candidate and what he brings to the table

PM for more information

Hi all

One of our companies is looking for staff (3-6 members) to set up a new team in Europe. If you are interested in Cryptocurrency, Blockchain and tech in general (i hope, as you are here!) and are fluent in English, this might interest you.

What is required is the following:

- Ability to work from home (fast internet)
- Motivation to work in a goal driven environment
- ABLE TO DEDICATE YOUR TIME TO THE JOB (students OK, if you are fulltime hired somehwere else, NOT OK)
- Ok to be paid in Crypto
- Insured
- Meet once a month in Switzerland or Dubai (expenses paid by company)

The job will be in the client management and operations management part of the company. English is a must as well as good computer skills (no need to be a developer but basic tools must be known). More details in PM

Now I know its a highly controversial topic, it's been discussed up and down but honestly, best content so far I could find when using the search function are posts dating back to the time of Mike Hearns etc.

I fully disclose that I am on the side of team "increase the block size", at least to 4MB for now but what is it that opponents worry so much?
It is absolute clear that all the arguments against increasing the blocksize are not justified, at least not anymore considering the current miner landscape.
Lightning is not the solution. Not for me!

So what is in the way of going there? most miners would support the change.

Aware that with 4MB, we would reach the limit again, but at least for now, BTC would be back to be what it was

Then talking of which, why not reduce block time to ~5 minutes while we are at it? Whats the exact trade-off between 5 and 10 minutes?

i love it. this thread makes my day.

so in this beautiful logic: a casino has not been robbed, hence you don't get robbed in a casino

i could also assume that i am not getting killed in a hospital, since hospitals don't kill people?
