It is possible to do money laundering via Bitcoin, but there is no assurance whether you won't be traced.  Bitcoin has a transparent blockchain so it has high traceability.  But many solve that with mixers.  But still whether laundering can be done through BTC or not, we should not encourage anyone to do that because it is a bad thing and also, will give a bad image on the cryptocurrency industry.

It could happen of course but it depends, from a practical point of view a single individual trying to hide his wealth from the government or any other institution could do it as long as his wealth was kind of low, however if we are talking about very wealthy individuals or even criminal organizations this is not really practical for them, most likely what they will do is to bribe local banks to help them in their money laundering operations.

This process is a lot more simpler than what they will have to try to do to launder that money with bitcoin, as they will save themselves the fees, the costs of converting their money to bitcoin or any other cryptocurrency and then back to fiat and the trail that they will leave will be more difficult to follow than what you can do in bitcoin, so all in all for criminal organizations it doesn't seem to be any advantage to try to use bitcoin for their operations and most likely this is why it's not happening right now.

binance is the best, they required 2 BTC withdrawing without KYC. but the problem is how to deposit fiat.

The increased value of bitcoin ease the process of money laundering. Right now more volume of funds get transacted through bitcoin than other days. Right now if we make a transaction it is possible to transact a huge volume compared to the days of bearish market.

Whats the reason for Money laundering ?
                      People doesn't wish to pay taxes to the government. To avoid tax, the excess earnings in fiat will be converted to bitcoin and kept hold. If required can be transacted directly to different locations as well as can be cashed out on requirment.

yes some people use bitcoin for money laundering because after entering the blockchains all transactions will become anonymous so they cannot be tracked
This is the reason some countries do not accept bitcoin as a means of payment because legally bitcoin will make it easier for many people to do money laundering and embezzlement.

Before using Bitcoin in money laundering, they've used banks and people to launder money. The evolution of the technology makes their tactics evolve so they could easily make a dirty money in a clean money without being trace by the Government or authorities.

In order money laundering to be a success, they use this called "layering that transfers the money in smaller amounts to many account, buying properties, while in Bitcoin, I bet they use many Bitcoin addresses as much as possible and buy other promising cryptocurrency to be untraceable as much as possible as well.

It is entirely possible and it is long standing adversary of bitcoin that prevents it from leaving a sour taste in the mouths of public. The key problem with bitcoin as a medium for money laundering is that most blood money is in fiat form which means that you need to convert it to electronic which could raise suspicions. P2P is the best way to make money laundering via BTC work, this comes with a problem as law enforcements also knows this modus operandi which means you could be trading with a decoy and the trade was a money laundering sting.

Ok since it has made obvious that people do money laundering in respect of bitcoin, is it a crime?
Since it has made clearly that after purchasing bitcoin it will still be converted to fiat currency, so how can we detect that the objective of individual to buy btc is because of embezzlement of fund's, I think a robots suppose to be implement or create for monitoring the rate of bitcoin or amount of btc in someone's wallet in order to identify money laundered.

I think it can only be possible in places where the government doesn’t have their eyes on what’s happening, but as long as they have their eyes on everything you can get caught with whatever you’re trying to do. Bitcoin is not really as anonymous as some people make it seem, if you commit crimes with it there is still the possibility of getting caught.

I even saw a post by SWIFT where they said that people who are into money laundering prefers to make use of cash and not even Bitcoin. Anyway, I am not in support of all that, people who commit crimes should be punished for it.

Laundering means to transfer illegally obtained money or investments through an outside party to conceal the true source. Money laundering means sending illegal or stolen money to a foreign bank to hide the fact that the money was illegally obtained.
Billions of dollars have been laundered through cryptocurrency exchanges. Bitcoin business is one of them. Money laundering is a major problem for the world economy. According to a report up to $2.8 billion has been laundered on exchanges using bitcoin.
Placement, Layering, Integration are the stages of bitcoin money laundering. But bitcoin laundering is a practical and cost-effective option for cyber criminals. Money laundering via bitcoin is not a good idea. Laundering via bitcoin leaves a permanent trail. The mission of money laundering is to create a chain of transactions that can’t be traced, so since the bitcoin blockchain is designed to have an indelible public record of all transactions. It's difficult to launder money via bitcoin.
So, it can be said that money laundering via bitcoin is not easy at all.
