what is the advantage and disadvantages of wallet mixing? why do i need to mix my coins in my wallet? This question is running to my mind about wallet mixing.

You mean bitcoin mixing, right?

Well the advantage of mixing your coin is that gain more anonymity as the coin that is sent to the recipient is not tied directly to your coins, meaning that you in the process stay anonymous. Since bitcoin is a public ledger, anyone can view transactions and still has the potential to reveal your identity.

Disadvantages, well it can be costly, especially for large amounts to be mixed.

Exactly, you mix your coins so that you became anonymous and somewhat "confuses" anyone that it trying to tracked your every bitcoin transactions. Blockchain.info can reveal where you spend and how much bitcoin in your wallet is. So if you want to remain "anonymous" you have to used this mixing services. There are a lot of mixing services out there, if you wanna try just click on my signature.  :)

In addition to what has already been said, some disadvantages include having dirty coins of somebody else and that may get you in trouble, but the chances that you will keep getting them from the same person over and over are so low that can't even be considered as a proof that you have done illegal things. If you're not into drugs etc. and you want to keep your anonymity I suggest using a new address each time you want ton receive some funds and deposit to exchanges then withdraw from time to time, It will mix your coin (probably not that effective) but will cost you less.

If coins mixing is so effective and a solution for dirty coins then why high level people from deep web markets and those who has enough coins to pay theses services wont used them to clean their thousand of coins?
They always got caught. I can't believe they are so stupid to make little mistakes that send them to jail.

lol? They do use mixers or use other "privacy-type" altcoins like Monero or Zcash (like... always);
And they never get caught because of their coins getting tracked. But instead, most of them make common mistakes that make them look dumber than they are.

Since I don't think you know shit about what you are talking about, you should definitely read those articles to know how Ulbricht (Silk Road) and Alexandre Cazes (Alphabay) got caught:

That is only if you are trying to obscure the data trail. It is not that effective against government institutions and such, but the common Bitcoin user will have trouble following a common mixed chain. Services do better than the individual, but I would never count on that in a situation where you are trying to hide from the government or from something like that, they have the software to analyze the numbers going into and out of the mixers and will eventually get you.
