Checking transaction history before accepting deal?

[dkbit98]

Do you think people should check transaction history before accepting any deals on bitcointalk forum and exchanging coins with other people?

There are many hacks (last case was Twitter hack, or Plus token scam) and hackers with addresses blacklisted by big exchanges (like Binance, Coinbase etc.)

In theory someone can try to sell coins in bitcointalk forum with lower price just to avoid locked coins in centralized exchanges.
Member that purchased this coins can have problems in future when he tries to spend or exchange them.

Few websites I found for checking BTC addresses:
https://www.bitcoinabuse.com/
https://scam-alert.io/

What would be the best thing to do for regular members and newbies before executing trades here?

I don't normally trade with newbies and I normally forget to ask for the source of the funds lol.

It's generally good etiquette to tell someone if your funds have come through a mixer or from a gray source and it's good on the other side to ensure you're paid to a wallet or a dex that can't have muted transactions so it's why I don't normally bother. In the real world, you can do cash trades for items up to £5k+ without even getting someone's name/history on the item so I don't feel a legal obligation to obtain one here.

There is a legal stipulation from exchanges that you shouldn't pay in funds that aren't yours and in a lot of countries its a legal thing - its even a legal requirement in the UK unless you're dealing directly with a government's investment.

Same here, but I don't trade often in general.

After all, good points mentioned by OP. I would expect if someone wants to get rid of his tainted coins here, the traded amount would be quite big. For small deals, it would just be a waste of time for them to try it here. 

In cases of large deals websites like

are most likely worth a try. However, I haven't used one yet, so I can't say how reliable they are, maybe tracking can be circumvented by transferring the BTC a few times to new addresses. There are few sources giving them credibility, so it's far better than nothing if you are not sure:

It is generally unwise to send bitcoin to anyone claiming to double your BTC. If you come across a bitcoin scam address, you can report it to Bitcoinabuse.com. The site also lets you check whether a particular address has been reported as an address used by scammers, check report history, and monitor stolen bitcoin.

At the time of this writing, the Bitcoin Abuse website shows that there have been 115 reports in the last day, 680 reports in the last week, and 4,636 reports in the last month.

I agree. I haven't traded in the currency exchange board but I do check it out once in a while and all i see are small deals of $50, $100, $1000. I don't think scammers who have stolen large amounts of money which would attract law enforcement bodies such as Bitcoin worth $2M would be patient enough exchanging just small amounts of $50 yet bitcoin mixers are there.

I believe if Someone even posted a deal to exchange BTC worth $20K in that board, It would raise suspicion. Nonetheless, It's good to be careful on what the source of the coins might be though it's a little hard.

Honestly, I don't care much on where bitcoins come from. In contrast, I mostly care on where fiats come from. There are a few more sites for you:

• https://bitcoin.org/en/scams

This is possible that has already happened here in our forum. But I think only a small amount which is scam investigator services wouldn't pay attention such as a small amount of Bitcoin transfer. Unless, if that is bulk transactions that worth of million dollars.

This thread might remind us to avoid dealing with newbies or it's better to check first the transaction before you will be accepting the deal, just like exchange Bitcoin to your PayPal.

I have doubt that the recent twitter hacked, hackers probably let the Bitcoin sleep on the wallet for how many months before they will exchange.

I trade not infrequently peer-to-peer either on BISQ or on this forum. I've never been overly concerned where the coins I am receiving have come from for a number of reasons:

Firstly, I almost exclusively trade with established/trusted/highly rated users, who I think would be highly unlikely to be involved in such scams.
Secondly, I do not use any centralized services which would investigate where my coins have come from and potentially freeze them or lock my account.
Thirdly, if I am concerned, then I can just mix or CoinJoin them.

If people are concerned about the source of the coins they are trading, then it's entirely up to them whether or not they refuse to do the trade. I don't think we as a community should be encouraging the view that some bitcoin are more equal than others, though, and diminishing the fungibility of bitcoin.

I never ask the source of the funds with anyone I trade eversince lol. Though never trade with newbies or anyone who isn't trusted enough here so I guess that's okay.

A bit off-topic, but i wonder if there's escrow who wants to do specific things (such as checking the coins is part of known bitcoin from criminal activity with public database as the source) before deciding the transaction is deemed success or not?

Never tried this yet, and the same with others, I guess.
