Bitcoin is being used for money laundering there's no doubt about that, but in his case, he is unable
to defend his introduction of bitcoin properly resulting, to a negative image of bitcoin. But introducing
bitcoin is never easy but if you were to introduce it you should be able to answer the question they may
have to convince them about the possibilities of bitcoin.
I actually do, I have introduced him the exchanger site that i was only recommending. That site is somewhat similar to coinbase it follows a KYC policy to prevent or lessen money laundering.
He really is a smart guy, the other 2 jury doesn't have any single idea what are we debating during that time tho
Then this jury is focusing on bitcoins risks. but rather than letting him focus on one problem you should've
presented other features of bitcoin(I'm sure this will bring more questions) to expand his knowledge about bitcoin a little more
and stop him from focusing on one problem. while you are explaining bitcoin he will realize the other problems that bitcoin has, but putting a little solution to that problem(just like KYC policy) will lessen the weight of the problem, and you should highlight the benefits and possibilities rather than focusing how to defend one problem.
Anyway, are you going to have another thesis defense?
The best way to answer a question is by returning the question. If they ask that bitcoin is prone to money laundering ask them also if fiat currency is not prone to money laundering. If they ask that it used in black market then you return the question, is USD not used in black market, what are the americans used in buying illegal drugs, weapons isnt it US dollars. Then when they answer the question you will reply that bitcoin is like US dollars, it is a currency online and has value and thats why it is not the currency that is the problem but it is the users.
