I believe this is all an inside job.
I was victim to this shyt in the early days of crypto when only BTC and LTC existed on the market. I ended up losing a lot of money, and the website that went under claimed it was hacked. Turns out, after doing some of digging, it was more than likely an inside job to snatch and grab everyone's crypto in the cloud.
Lesson learned.
Crypto will bounce back. This isn't the first major exchange to go under. I still remember like it was yesterday when Mt.Gox went under. Crypto is here to stay, and certain cryptos like XRP and XLM have real utility that are already being utilized.
