Being anonymous have its pros and cons, it gives us freedom on how to use Bitcoin and other people are just using its anonymity in evil ways.
These schemas was for along time before bitcoin created.
Bitcoin is one of the instruments but not the reason
Yes I agree regardless if Bitcoin/block chain was invented or not scammers/crooks are going to this.
I believe in the future there will be a way to trace any fraudulent account or anyone who use his btc account to do any illegal transaction will be red flag from their system
I do not think this is going to happen, there will be a lot we need to sacrifice if this is going to happen.
