Looks like whoever is in control of MtGox's coins (is it still Karpeles? anyway) is selling, most likely creditors will get their money back finally and the MtGox saga will finally come to an end, which means all these coins will be in the hands of different people.
According to Coindesk, those coins were sold over "the past few months." Maybe the market was looking for an excuse to sell off, but it's a weird catalyst since those coins aren't really new supply. They were already sold.
There is also the coincidence of the Binance hack which coupled with the Gox sale, has made a lot of noobs panic sell.
Yeah,
that selloff when the Binance news broke was classic panic selling action. It's not too often that we see sustained selling like that in such a short period of time. That was a $1,300 2-hour candle. Impressive.
still an extremely concerning event underlining security vulnerabilities on Binance yet again.
Binance is the most popular crypto exchange in the world now and under regular attack by hackers. This is the 2nd time within a month their defenses have proven insufficient...
They need to improve big time, and compensate the customers.
Most exchanges have similarly insecure API token mechanisms that should be improved, but this absolutely isn't just Binance.
Bot trading accounts should never be used to store life-changing funds (especially because occasional bot fuck-ups can wipe you out anyway). And nobody should be allowing API access to third party sites like Coinigy. It's just insecure.
Don't expect compensation. This is why most sites post warnings when you go to generate API keys.
