I'm always supprised to see how many people think they legally own those funds... Both in the bitcoin world as in the FIAT world...
If i have 20.000€ in my bank account, and i have to pay a contractor, but i mistakingly send my hard-earned money to my car dealership instead, would you think it fair if the car dealer said: "this money is mine now".... Still, a lot of people get sent funds by mistake and think it's just an early christmas present dropped from the sky: it is not, somebody had to work long and hard for that money (most of the time), they mistakingly sent it to you... Keeping it simply feels wrong.

Eventough i'm not a lawyer, my dwindeling sense of ethics, fairness and honesty tells me that it's not because i mistakingly send the money to the wrong account, that it legally belongs to that account owner...

Offcourse, since transactions are irreversible, a lot of people use pseudonyms (or plain fake names), and they likely sent funds to users all over the globe... So i doubt they'll ever get all their money back, even if it's legally theirs...

easyest: yes
safest: nope

If you want to run a "real" mixer, it is imperative that you keep as little people in the loop as humanly possible... Giving all the hard stuff to a third party gives away any oversight you have. It basically forces your users to trust, not only you, but the complete staff at jambler. I would never, ever use a service that uses a third party backend for mixing... Those people are basically just affiliates that add just another potential attack vector without adding any benefits.

Next to this, i remember looking at jambler when they started out. IIRC, i had a bunch of misconfigurations, vulnerability's and other problems. I have not checked if they fixed them, but i took a quick glance today and it looks like they're still implementing a MITM right into their workflow by continuing to use cloudflare... I really don't think they fixed their other issues (eventough i did not check this... I would not touch a privacy-centered service using cloudflare with a ten foot pole).

I learn something new every day... This was the first time i heared about the SigNet... It seems like a "better" testnet. I have no idear how i missed this info
https://en.bitcoin.it/wiki/Signet

Regtest is great for small scale tests, but the lack of a real "network" has stopped me from using it for large scale tests... It is, after all, a network in a single box...

yeah, sorry, i stumbled upon this thread because i was mentioned in it and i failed to read that you actually received BCH payments and were not merely trying to claim the "airdrop".... If you actually received BCH, you should indeed be able to spend it by importing the seed into the bch electrum client AFTER you emptied out your btc electrum wallet.

Sorry for the confusion... The main point still remains: you should be able to spend the bch aswell, as long as you spend your btc first (in theory you can spend your bch before you spend your btc, but this is not advisable)

As long as you do it in this sequence (first spend the unspent outputs on the BTC network, only then start spending unspent outputs on other networks... There are at least 4 or 5 forks that have *some* value) you should be able to do this, yes... As long as those unspent outputs were funding your addresses before the BCH fork, you should have some BCH waiting for you...

Do realise some of these forks have serious security issues... So (like you already said yourself), first move your bitcoin to a new wallet, then start messing around with the forks...

A quick google search turned up a list like this one (i'm not affiliated with them, use at your own discretion): https://forkdrop.io/#table-bitcoin

Sorry, but your story is all over the place... it's very hard to follow what exactly happened...

Am i correct in saying that the problem is:
you sent funds to an exchange, but the exchange did not credit your account? You checked a block explorer and you see the address given to you by the exchange was funded... the address you provided (3LXFcCGTmWWeqJ5oQMx6eVsSRj1Qx8xwME) is indeed funded with ~4  BTC, but it's hard to understand where this address fits into your story.
If this is incorrect, maybe you can try to explain the problem in 2 or 3 phrases, just the problem, not previous tests and stuff..

It might also be easyer if you start naming names: which wallet, which exchange, which address, which transaction id... Do realise that posting addresses and transaction id's decrease your privacy, but nobody can use this data to steal from you (unless you start giving away seed phrases, private keys or login details to the exchange)

yes, the size (or virtual size) matters... This has nothing to do with the value that's being transferred.

Size is determined by the #of unspent outputs being used as an input, # of new unspent outputs being generated and the type of wallet you used... And a very little bit by the type of the receiving address.

I only hold a very small amount of alt's, but most of my (limited) portfolio is invested in BTC... So i usually check preev.com about 10x/days...

Well, that's exactly the sollution detailed in the thread i linked to... replace the content by an empty json element ({ }) 
The content of the file is merely saving gui settings anyways, so replacing the content with an empty element...

A quick search on the forum turned up this thread:

https://bitcointalk.org/index.php?topic=5319613.0

Can you read through and try the sollution suggested therein?

@magneto: completely correct... I focussed on the technical part, but you do have to have quite a bit of BTC in order to setup a proper mixer. If you don't have enough coins, you might start dispersing tainted coins, and people won't like that... And it's true a good mixer operator will have a fulltime job running his mixer...

That's a rather tricky question TBH... Monero is a privacy-oriented coin, but if you buy a hardware wallet online using a credit card (or paypal, or wire transfer) and have it shipped to your home, then buy monero on a KYC exchange using a credit card (or paypal or wire transfer) and withdraw said monero to an address generated with your hardware wallet, i'm pretty sure certain 3 letter agencies will be able to track you down if they really wanted to.

You would have to buy the monero P2P using cash, then transfer it to an intermediate wallet (so the seller loses the trail) and then move it to your hardware wallet... I guess that would make it harder to track.

Anonimity is a bit of a discussion point in this community. I, for one, think it's perfectly fine if you (or anybody else) don't want any invasion of your privacy and start using mixers, coinjoin or privacy coins. Others will probably think it's sketchy...

Ugh... Their next victim...
Sad to see people are still falling for their trap.

They have a long history of selectively "closing" high-value accounts because they were flagged. They refuse to give any comment as to which algorithm they use for flagging accounts, and they ask over-the-top ridiculous things in order to unlock your own money. This includes, but is not limited to  providing screenshots from incoming transactions, proving where your money comes from, photo or videochat, paying for notarised translations of private documents and  providing your social media account (https://support.freewallet.org/support/solutions/articles/9000184127-how-to-pass-kyc-procedure-).

Their modus operandi seems very similar everytime:

• they block a high value account
• they refuse to say why
• they ask ridiculous, over the top KYC questions
• they are slow and repeat the same questions over and over, sometimes stretching the process for months
• they hope their victim loses interest in the matter, so they can keep the money (this is just my feeling)

The only thing that SOMETIMES seems to speed up the process/solves something is making a lot of noise... They seem to be sensitive to negative publicity in some way... Post on bitcointalk, PM them the link to your post (they are active on bitcointalk and will probably jump in this thread sooner or later), post on facebook, post on twitter, make blog posts about them, rate them negatively in the appstore, get a lawyer,... The more noise you make, the higher the chance of getting your issue solved, or at least, that's what it looks like for somebody who has seen dozens of these threads accusing them of theft.

The best example of noise is what they did to Elon Musk: the selectively closed his account, but he only had to tweet about it once to get it solved... Why? Because having Elon Musk tweet something bad about you is bad publicity. Bad publicity = less users. Less users = less accounts to selectively close. Less accounts to selectively close : less income.

I've created a concept for somebody several years ago.
In it's essense, a "classical" bitcoin mixer isn't all that hard to understand... Just generate a mixing session where a user submits the address where he wants to receive clean coins, present him with a deposit address, monitor said address for unspent outputs funding said address, calculate how much clean coins the customer is entitled to receive and then create a transaction using a wisely chosen set of unspent outputs.

The real "magic" is chosing the correct set of unspent outputs. You can do so by seperating the "receiving" wallet and the "sending" wallet, maybe even on seperate machines, maybe even by deriving "receiving" addresses from an xpub, so you cannot spend the incoming unspent outputs, maybe by using things like exchanges or services with hot wallets, maybe by coinjoining, maybe by using other mixers, maybe by just tumbling your coins. You'll defenately need some knowledge to make sure your customer will stay happy, if he receives coins from his previous mix, he probably won't like your service.

On top of this, you need bulletproof hosting, DDos protection, a hardened (multi)server setup, darknet presence, anonymous tld registration,....

You'll also need to think about things like a letter of guarantee, output tuning, fee rate estimation, randomisation of the type of unspent output,...

Defenately not an easy task. With the current crypto climate, i wouldn't dare of writing up a mixing service anymore. To much heat to bring to yourself... Also, you'll need a pretty competent lawyer, mixing might be legal in some countrys and illegal in others...
My proof of concept many years ago was made up of a 3 server setup: a frontend sending PGP encrypted messages to the database and a backend hosting both receiving (watch-only) and sending (hot) wallet. Every server had his own keypair, all packages sent between any of the servers was always encrypted. The data in the database was also encrypted. The disks of the servers were encrypted. No logs whatsoever. The frontend was just a gui where the session was created, everything was stored in the db. The frontend had 2 network interfaces: an internal and an external. The database only had 1 internal interface on the same vlan as the external and backend server (the db could not be reached over the internet, it was patched using a fourth repo server that was turned off by defauld, had 2 network interfaces and was only started so the db server could be patched). The backend also had 2 interfaces: one on the internal vlan, one external interface. All 3 servers had a different OS/distro (freeBSD, centOS and debian), and each server was bulletproofed pretty well. The backend contained all code, everything was written in python, the wallets were connected over tor, and the peers were carefully selected.
And even then, it was ONLY a proof of concept i made for a thirth party, it was never brought into production. If it would have been brought into production, i would have had to bring in a second trusted dev to review my code, and move everything over to a bulletproof hosting facility. But this wasn't the initial setup anyway, it was not what my client had in mind to begin with, so we never did that.

If it's just a way for you to learn about the ecosystem: why not... If you're serious: honestly, i wouldn't touch your mixer with a ten foot pole after seeing you came onto bitcointalk and asked for a tutorial on how to create a mixer... Doing something like this correctly requires an above-average amount of knowledge about the bitcoin protocol, the bitcoin community, the scripting language you'll be using and proper system administration knowledge... It's not like you'll ever find a step by step tutorial that teaches you how to setup a good mixer.

Did i say it was idiotic? I did not say this... You're free to ask questions (especially if they haven't been asked before) and you're free to discuss any crypto related topics...
What i said was: i'm sorry, but when i read your post, i have no clue what altcoin, website or service you are talking about... You seem to be mixing questions about an HYIP (but you don't clarify which one), questions about altcoins (but you don't say which ones), questions about algorithms, questions about bitcoin,.... So you're still free to ask these questions, but you'll have to rework your post to make sure people actually know what you are talking about.

Your guess is correct, just right-click on the link and save the .asc file locally... Then use whatever tool you have installed to verify the signature.
If you have more questions: you can search the forum, and if you don't find the answer: don't hesitate to ask them here

Besides being in the completely wrong subforum (why on earth would you think some kind of walktrough? of a HYIP? belongs in the Development & Technical Discussion subforum), the reader of your post doesn't have a clue as to what you are talking about...

I mean, there are hundreds of craptokens and thousands of sites that allow craptoken "mining" trough some sort of game... Usually these sites are scams aswell... But the very least you could do is clarify what kind of ponzy, scam or hyip you are talking about (without actually placing a link to their site, you don't want to give them an increase in pagerank).

I'm not a monero holder, but i quickly glanced at getmonero.org.
It seems to be a project page listing the exchanges and reference wallet (plus links to other wallets). This means you wouldn't be buying your monero from getmonero.org, nor would you be storing them in an online wallet (unless you specifically chose to pick one of the online wallets from their list).

You'd be buying monero from an exchange... Which is where most people buy their crypto... You can do P2P trades, but most people get their crypto trough an exchange (AFAIK). Some exchanges enforce a KYC policy, other are more private...

Once you buy the monero, you can transfer them to a hardware wallet, yes... You can probably do this straight from whatever exchange you pick, there should be no need to go "exchange" => "intermediate wallet" => "hardware wallet"... Instead, go "exchange" => "hardware wallet"...Both trezor and ledger support monero... And yes, you'll have to pay a fee in order to make the transfer.

It might be a good idear to start a new thread instead of bumping a 4 year old one with a question that's not related (nor equal to) the question initially asked in said thread. It's called necroposting, and by doing this, you'll probably get a much lower response rate.

This being said, you didn't provide nearly enough information to give any meaningfull answer... Are you still able to log in? Do you see transaction history? Did you try to contact their support dept? Address, transaction id's,.... Without any extra information, other people won't have a clue as to what might have happened either.

So, what i would propose you do is:
1) stop posting in this thread
2) contact block.io support
3) if they don't answer, create a NEW thread with sufficient background info
4) realise that we are not block.io support staff... We don't have access to your account, we are unable to fysically give you your funds back... We might give you some pointers and some tips tough (if we have a gut feeling of what might have gone wrong)

I, for one, have not looked at this service in 4 years... My input might not be that good... I didn't even know they still existed.... But maybe by following above steps, somebody who used their service recently could chip in.

Sure,  but those "just extras" are pretty important... They make sure that master private key never ever leaves the hardware wallet... That's a pretty big deal, not something you should just catalog as "just extras".

By this defenition, a car is just four wheels and an engine. The steering wheel, chassis, airbags,... are just extra's.... They add nothing to the basic functionality of your car (which is moving automatically)...
