What really made me worried is that even the arrest has been done, there's a chance they might prove themselves not guilty once it got into court proceedings. All those investments were made through Coins.ph (Philippine's top financial services platform for Bitcoin) and upon checking by the company representatives in hopes to return all those money invested, it has been checked and emptied. The transactions that were been made was all untraceable, so its impossible to retrieve all those BTCs, thanks for its anonymity feature

Wow I'm really sorry to hear about this. People need to always remember that if it sounds too good to be true, it almost always is. I hope they are able to recover the coins, potentially offering these people a deal if they return whatever they've stashed. I find it hard to believe that they blew through $17 million, but hey I guess people can always find ways to waste money.
There are plenty of opportunities in Bitcoin and the crypto economy. "Get rich quick" is never as quick or easy as it sounds, it's a false lure.
Best regards,
