Man, hire a lawyer while he still has money and btc/properties. Once he has nothing left you can't do shit. Those who do it first will receive their money back, don't wait, it is a lot of money.
I agree with you. In fact, I have decided to create a platform of people affected to help each other and study our options to recover our Bitcoins.
I have contacted lawyers and I am waiting to receive the conditions to proceed with this issue legally.
The Platform is avaible in English and Spanish. We want to adopt a international common position in order to give our possible claim a significant weight.
