SDR and BTC

Today I listened to an interview with Lynette Zang from ITM traiding. She is promoting gold of course as that is her job. What she is saying is that BTC is only developed so that it can be replaced by SDR, the government run world cryptocurrency. Though centralization of SDR would imply a total vulnerability to hackers. The first serious hacker attack will put SDR out of business. BTC on the countrary is unhackable due to being de-centralized, only individual wallets or exchanges could be hacked rather than BTC itself. I do not see how SDR could be near as resilient as BTC is. Any thoughts?

Here is a video just for the reference:

Also there was a previous article on SDR on steemit with the reference to Lynette Zang https://steemit.com/bitcoin/@revelationquotes/sdr-as-the-new-reserve-currency-a-cryptocurrency
