Before Bitcoin released, which currency the offenders use for payment? Dollar or other currencies? Why do you just blame the cryptocurrency world while there are many people using FIAT for crime? Remember, Bitcoin or FIAT are currency and the primary function are help us transfer money.

BTC is very popular in any other country. So Bitcoin cannot be used with any kind of criminal activities. But we can agree that with the use of Bitcoins, those who are into ransom has increased their chances of not blowing up their cover.

it's not surprising that criminal activities increased after the release of cryptos. its because crypto offers fast transaction than fiat, anonimity and it cannot be counterfeited

crime is already there when bitcoin has not appeared, and I think it's not true that bitcoin is used as a criminal reason, here we help each other and exchange experiences, because now we can recognize it. each other and helping each other, for example there are people who commit crimes, it is the person whose responsibility is less.

If you say believe or do not believe in the criminality that associates bitcoin in it, we all know and hear it from the news that has been circulated. If the news spreads then it can not be said not to believe it. But we also can not blame bitcoin at all because bitcoin is a tool used for criminality used and bitcoin is not its suspect. If bitcoin is used for good use then bitcoin is not bad in the eyes of the law.

Criminality and Bitcoin are 2 interconnected thing. They are linked with each other. Antisocial people use bitcoin for their criminal activities. Money laundering type serious crime are done by the help of bitcoin and also illegal money transaction between terrorist organisation and criminal people because bitcoin provide safe untraceable transition between Clint and owner without involvment of third person like bank, government. Kidnapping, child pronography, bomb blasting, murdering type other criminal activities also associated with bitcoin.

everything give negative and positive side. like bitcoin, will give you 2 perspective.
people will use very efficient, i dont know for what. but it can use to helping people around or use to criminal

Bitcoin is made to be a tremendous step ahead to make funds safer and may also act like a substantial security against any kinds of financial crime. For example, bitcoins are fraud-safe. Users have the complete control over their transactions and are not able to receive unapproved costs like credit card scams. Bitcoin exchange transactions are irreversible and safe from fraudulent chargebacks. Bitcoin exchange enables money to be protected against identity theft and loss using strong and beneficial mechanisms like backups, encryption, and many signatures.
Some issues has been brought up that Bitcoin might be more attractive to scammers mainly because it may be used to make personal and irreversible payments. However, these features are already available with cash and wire transfer that are commonly used and well-established. The usage of Bitcoin for exchange will definitely be exposed to similar restrictions that had been available in current financial methods, and Bitcoin is unlikely to stop criminal findings from being carried out. Overall, it is popular for crucial discoveries to be thought of as being debatable before their advantages are very well recognized. The Internet is a great sample among others to illustrate this.

Unfortunately that is true. I even believe that the fact that bitcoin is rising very fast has reasons behind it and that reason is the black world (criminality, drug traficing etc). Anonymity of bitcoin is playing very important role for this.

I wouldnt say increase. Its more of it made it easier for them and made it harder for the authorities to apprehend them. The number of criminals is difficult to estimate at the same time, you cannot gauge the direct correlation of such an increase to crypto.
