i think the use of bitcoin for illegal activities is not such a big problem, because if a local and regional currency can be use for illegal activities  and the stage cannot stop them then how can we thing about the universal currency which is also anonymous. so the government should stop the illegal activities rather than to find what kind of currencies are they using.

Same goes up for fiat related transactions. Even if you use internet banking to send money, no one will be knowing what the purpose of that transaction was. And especially when it comes to cash money transactions. Bitcoin isn't any different. It's a currency that is being used for all kinds of purposes.

How come you know the stats? Any valid source of that percentage you are talking? lol.

And no, bitcoin is prominent today because of it's price and not with the "only" reason you are pointing about more people are using it in business. The stats today for business who are using bitcoins are far away from so called big adoption.

Are you sure safe using bitcoin for illegal acitivy so what you can buy with bitcoin "drugs,weed or what". in fact bitcoin only most use for gambling site so what a problem with that in some country, gambling isn't illegal.

yes it may be but i personally have no idea, to me as bitcoin is a new born currency and still hardly 1% of the world population will be using bitcoin,and the one percent are those people who have good command on computer and internet, and well educated, so i can say that the illegal bitcoin users will be negligible, and i will like to add that most of the people of the world will be using the most popular currency of the world which is almost in every country is applicable, therefor USD is the best option with them using for illegal activities.

yeah by law in some countries gambling is not illegal, but morally gambling is illegal everywhere i every corner of the world, as with that a person lose all the hard earned money of his life and ruin his life to enter the poverty.

but the crimals dont know bitcoin but not all so its ok if they found out bitcoin druglords will use
bitcoin instead sending money in the bank and other transaction things

Bitcoin can help a lot in money laundering practices so its nothing new that bitcoin is being used for illegal activities and it will continue to be used as long as it provides a way of minimizing the risk of getting caught. With the fiat money risk is bigger for example when you do the exchange of the money something may go wrong and starts a mass shooting. With bitcoin criminals can talk to each other from TOR, from SIGAINT email which are untraceable and make a hassle free exchange.

Thanks for saying this, it's a really important point that a lot of people both in this forum and in the wider world need to understand. I can use dollars to do illegal shit, just as I can use bitcoin, in fact I'm probably more likely to use dollars in person as cash is LESS traceable than coins(without using mixers).
