so, in this way the  people are doing illegal work through it .they should punished badly so that anyone cannot do  it again and i know the illegal work is increasing because of movies ,they make such types of movies and they follow it in their real life.

It is because bitcoin is not being monitored for now. Actually government are protecting their asset so that economy will not going to fall down. This is why ahynfiat currency has to be limit when someone carry it going outside to another country.

Fiat currency has really no value in terms of physical aspect but it is the representation of the value of the economy that is why unlike bitcoin fiat is being accepted by the government. Bitcoin is more like an asset and if one day if bitcoin will be acknowledge pretty sure that it will also be limited to carry or hold sort of bitcoins in going to another country and that by means that every bitcoin holders will do KYC and all exchanges will require doing it. No more decentralized aspect for if it do then government will never acknowledge bitcoin like they did now. And if bitcoin could be in a way like being a trouble to government then it will be ban like other countries did.

Bitcoin was conceived as free "money". We cannot talk about its purpose, since people themselves choose how and where to use it.
If some of the transactions take place in the shadow field, then it should be so. I am pleased with the fact that the share of these shadow funds does not exceed 5%.

Is it really that small only? But why most people think of something illegal first when they hear about bitcoin. They only know that it's been used by the criminals in the black market but they don't really know what's the real purpose of it.

I'm fortunate to be familiar with Bitcoin, so there's no need to evade taxes by keeping gold in my ass hole. I can understand the reason
the person did this, because 18% tax was a very large amount. Hopefully someone tells that person about Bitcoin, so that person won't
do anything else weird to avoid taxes.

Everything depends on your own experience bitcoin usually increases its price based on the transaction. Rising currency prices will lead to scams in which case keeping them in a secure wallet will reduce the risk of many people not being able to access them and will result in digital assets. Bitcoin is more expensive than gold and if a person has the ability to provide such products or services he can sell it for bitcoin if he wants. Bitcoin can be used to buy and sell online in the same way that we shop online.

It is really disgusting even when reading the news. Yes, nobody can do something like this with Bitcoin because of its not being a physical currency. But unfortunately, this doesn't mean that bad things like money laundering etc. can't be done on a digital platform. I hope that can be prevented more than now by increasing the security system to a much more better level in the future.
