Most of the time you don't know.
Because even if you can track the source of tokens from the blockchain, you still don't know what's going on.

[Heisenberg_Hunter]

You can't track btc. It's anonymous and is developed for being anonymous. Moreover people use mixing services so that their coins won't get tracked. We don't need a KYC for creating a wallet, but when we need to exchange them we need a KYC. The public ledger so called blockchain is pretty difficult for criminals to hide with their money. The guy who needs to sell may be in a tough situation for immediate money or he might be afraid to sell such a huge money so that he might be caught with law enforcement.

Unless you are sure with the guy, buy them.

It could be yours if you buy by meeting each seller, and if you buy the way you send your money first, you better do not do it, because it could be fraud, that's my opinion.

that acceptable i guess buy and sell is have some agreement in it, when someone sell it that mean that man wanting to getting profit in it, and you as a buyer cause you seeing a need in it and you need that too

There is such a concept known as "tainted coins". You can read the inputs on this link for more information, but basically, since Bitcoins can be traced, it's possible to know which ones have been stolen. It's not very reliable though, unless you've actually followed the traces of a hack from its origin. You probably could get in trouble for buying stolen coins, but only because authorities might think you're the thief or are related to the heist.

As for whether or not you should buy in that situation, remember: if something is too good to be true, it probably is.

This is poor logic. I imagine everyone has been involved in handling stolen cash/counterfeited cash. Doesn't mean they are guilty of heists/making them. Bitcoin is the same, and identifying whether someone has been involved in a hack/heist or what ever would actually be difficult after a few transactions. Especially with the amount of mixing services/exchanges which just make it easier for the transactions to look legitimate.

iT is acceptable if you both agree on your each terms, actually there are a lot of people who do buying and selling bitcoin by meetups but of course be very cautious on every transactions you do specially if it is what you said BIG AMOUNT, your life will be on danger too, if the man/ woman you want to trasact is a scammer or kidnapper, all your work will be gone. Actually if you would buy cheap bitcoin and the transaction of the both of you succeed you will gain a lot of profit.

[eternalgloom]

I'd be more concerned that it was a scam, rather than stolen coins or something. I mean why would someone sell way under market value?
On what platform have you received such a deal?

Will,its up to you if you accept that offer,but for me i thinks there something fishy in that kind of aggreement that there someone approaching you to sell his bitcoin at low price,but in big amount,because in reality theres no sensible person would offer this kind of treaty,especially now that bitcoin will pump again in the market,so in order to prevent that kind of dishonesty strategy we must always vigilant in every transaction we made.

It is a negotiation on an exchange that can be uncertain. I do not have the habit of believing in such direct conversations. There will be no stolen bitcoin or they will use them as a way to scam and occupy large amounts of money from you. Be careful and learn about them.

[BitcoinHodler]

USD EUR conversion rate is 0.83 right now according to google. if someone approached you on the streets and said he is going to give you a good deal on his EUR with a nice discount will you do the trade with him on the street? (assuming you have a way of telling the EUR is not fake).

I agree, which is why I said it's generally not reliable. I'm just saying the concept exists. I've never heard of anyone running into trouble because of it, but, if you somehow end up with it, and chain analysis services trace it back to you (considering exchanges and mixers could be forced to give up info), you could get questioned or something. For example, let's say there was a hack, and someone sold you some coins peer-to-peer. You sent those to some exchange or an address that is linked to your identity, but it turns out those coins were part of the hack. From there, you would potentially be a person of interest and could even be considered a suspect -- not automatically guilty. It must also be noted that I was merely citing a remote possibility.

Bitcoin Gold is a distributed digital currency. It is a hard fork of Bitcoin, the open source cryptocurrency. The stated purpose of the hard fork is to restore the mining functionality with common Graphics Processing Units (GPU), in place of mining with specialized ASIC (customized chipsets), used to mine Bitcoin.
 
A central part of the bitcoin process, mining, is being controlled by a few manufacturers who sell their products to a select group of industrialized miners, centralizing the mining task and breaking with one of the core values of bitcoin - decentralization[2]. ASIC resistant GPU powered mining provides a solution, as this kind of hardware is ubiquitous, and anyone can start mining with a standard, off-the-shelf laptop computer.

It depends on the situation, if authorities are keep on tracing every transactions of that stolen Bitcoins and you bought it, then you are already in trouble because it is now possible to trace Bitcoin especially if you use an exchange to convert it to cash. This is also why it is better to just buy and sell cryptocurrencies on exchanges. But if that stolen Bitcoin is not being traced then it is acceptable and you will be fine. The problem is you'll never know if you bought a stolen coin to a stranger or people you only meet on the internet until the police arrested you.

This is a serious red flag. Why should this guy want to dump his coins, at prices much lower than the global exchange rates? Ask him why he is doing it. I his answer seems satisfactory to you, then you can proceed with the purchase. You should be cautious. But at the same time, you should not ignore any profitable deals.

I think it's hard, you can track the transaction to see if it comes from a hacker's address. Not only stolen bitcoin sold at low price.

[Aura]

Tainted Bitcoins are not being listed for a lower price, why would they do that? I am sure that 98% of the Bitcoin users don't know about tainted coins nor know how to check whether is tainted or not. Also it's not a legitimate reason for exchanges to connect you to crimes. If you really care about it, then use one of these mixer services that make the history of the coins completely useless.

Like you are walking in the streets? If you want to know on where those bitcoins came, you can trace the address on where it came from. There were people (legit) who are selling volumes of bitcoin to a casino here in my country and they are really a lot of it somewhere around 2,000 but no one wants to take the deal. It's hard to know if those btc were stolen or hacked if it isn't then the guy just wanted to sell it for quick profit and dump it totally.
Are you in this situation OP?
