Probably their using mixers to stay anonymous, even with a public ledger to track all BTC transactions. This is probably different from all the other hacks where exchanges and e-wallets could immediately take action, and freeze those accounts if its peer 2 peer BTC transactions. Especially if they could convert it to other private secured Cryptocurrency such Monero, Dash and Zcash then back to Bitcoin again which makes it nearly impossible to track.

But I guest that the perpetrators wont have a ball to transfer that money into cash. It still confuses me that they have been holding those bitcoins for too long. Or maybe these coins have already been transferred to others. Laundering bitcoin is quite easy since there are many coin mixing on the internet. But the process is tougher with more than 120,000. No such coin mixing can have that much money to help those criminals.

Maybe they will try to split those coins as small as they can so that they can use it in the dark web or online bitcoin stores which do not need to require identity or KYC

The scammer who steals that amount and waits so long to move a part of it will not be stupid to send it to central platforms or use a mixing service, but rather he will have enough money to set up his own mixing service or even create an exchange.

That money can be used for a lot of things which after a long time can be considered profits and it will be very difficult to keep track of those currencies.

We are talking about the extent of the platform's willingness to pay to gain access to these currencies, and even if it did, the chance to recover it seems slim and scammers who have enough money and time.
I think the equation is on the side of the hackers

wallet address should be marked as a dangerous wallet address so that every transaction is logged so that they have a little trouble moving their funds or exchanging them anywhere, even though it sounds difficult because they always have the sense to disappear from there, until now I'm still asking if bitcoins can be hacked , except for just the careless people holding it, somehow I'm sure it's the bitfinex people who hacked it, but I don't want to accuse it either, but keep paying attention to the next news about this fund

Or they could spend millions in gift cards 
Jokes aside, over the long run the more moves they make the higher the chances they will make even the smallest mistake that eventually will allow forensic experts to trace them back from the start. Don't you think?

Even the large exchange is not safe to protect your money, these hackers are now increasingly intelligent to commit their thefts

Even if we know that everything that happens on the blockchain is forever recorded at the same time this hack happened a long time ago and the hackers had several time to think about how they are going to cash out their profits.

This means that if the are moving their coins now they have a very well thought plan that they think it is going to be good enough to fool anyone that tries to discover their identities, besides with such a huge amount of coins they stole they do not really need to cash out every single one of them as long as they can cash out some their lives are set for life.

120,000 Bitcoin is exclusively a large amount already to be imagined which is explicitly showcases how brilliant those hackers really are to stole such a big amount of Bitcoin. Now with Bitfinex experiencing a large amount of hack which is $30 million, it seems like even big and reputable exchanges just like what happened recently to Kucoin shows that their security have been manageably being entered by those intruders stealing a big amount from those exchanges. I just that may the Bitfinex manage to catch those hackers or may at least get back those stolen Bitcoins from them.


Probably that is the case. Professional hackers have worked out of this case and they may at least well established a plan on how they can get out of this mess and make themselves be able not to be caught by the authorities because of the crime that they have done.

This pretty much explains everything as to why these hackers will remain unknown and very hard to be caught. Considering the amount of money in their possession and its indeed a very one sided story for the scammers.
The longer they're holding these funds the higher the possible profit from their capital of the scammed amount they get, and I guess it became even slimmer the chances of getting caught.

Hello, I have received 547 satoshis at my usual payment address, it is from a very strange origin ... does it have to do with the movement of stolen BTC?
