they have been saying this  since the bitcoin start  , even the fiat also use in illegal transaction so i dont see any problem . it is depends on the person how they want to use their BTC .

Most of the people think Bitcoin is for illegal activity and stuff and I have to say that's not how it really works. You might be right Bitcoin is used for illegal activity's but its not just for illegal activity because most of the other people see Bitcoin as a future currency I also know few people how are investing in Bitcoin instead of gold and stuff, Its just being smart and knowing how to keep moving your money and make profit.

Why only bitcon, all valuable currencies like USD, Gold etc are used illegal trades. Not in India all over the these things are happening over more than hundred yearsBitcoin is a decentralised, digital currency. Its quiet difficult to find the bitcoin trader. Bitcoin has become the most valued currency. Bitcoin is first used in illegal trade by ransomeware hackers. This news has created a bad impression about bitcoin all over the world. Now countries like Australia, USA are banning biotin by having security reasons. Bitcoin or any currency have no right to enter into a trade, it the holder of that currency.

thats not the currency there is no exclusivity and the same could be said for normal currencies like pounds and dollars. 
A lot of tokens offer more transparency than real world money.

you can notice about other things, that were used for illegal deals or any motions, like people you hear some terrorist used facebook to communicate with each other, or even a orange revolution in some county with it, and legal or illegal way, people always can do because they choose, and the government can ban for some things for sure, but is no easy ofc

Bitcoin is just a currency used like fiat currencies to legal or illegal activities, depending the persons and their goals. Its not in any way the fault of Bitcoin itself but some people used money since hundreds of years (even before the Bitcoin's creation) to fund crimes and illegal purposes.

Any ordinary money that is used as a means of payment can be used and used to commit a crime. No exception to this general rule is bitkoyn. However, this does not mean that bitkoyn should be banned or restricted. For example, a kitchen knife or a regular fork can be used for killing. No one at the same time raises the question that these dangerous items must be banned. Now many state and non-state structures that suffer losses due to the distribution of bitcoins benefit from spreading rumors about the danger of bitkoyin in order to discredit him and cause negative public attitude towards him. It is necessary to react less to such topics.

Human can use any currency for illegal activity. Its not only bitcoin for the blame. I see some people on the internet used to blame bitcoins for illegal activity. Yes bitcoin transaction is not trackable but why they should only focus on the bitcoin transaction while there is so many other illegal activity using fiat.

That has been one issue that has been bothering people about the use of bitcoin and even made some countries create policies
