Hmm haven't we discussed this to death?
It is not possible for the police or any entity to tell, just by looking the transactions themselves. In fact, without any actual link to evidence, the transactions can't be identified. If the authority can get one of the addresses/transactions involved, they could get the whole link of addresses that are related but that isn't possible all the time and its rather inaccurate and useless.
indeed bitcoin is a criminal when we can not be said as a criminal, we are not stealing and even hacking a bank that exists in various countries. we also get it by own business and not concerned with the government or certain parties that exist in the country itself or other countries and even other countries have already agreed with the existence of bitcoin and already recognize this bitcoin. this is what I submit and I can distribute in this forum so and thank you.
