The very threat to CBDC is XRP for me, not BTC.
Even without the arrival of CBCD, the future of XRP is uncertain, as far as I know the lawsuit between XRP and the SEC is not over yet. So investing in it now is extremely risky, if XRP can't win the case, the possibility that XRP investors will lose everything.
We have more options than XRP, we don't need to risk that meager profit. Regarding altcoin investment, we have BNB, the return is not bad, I will choose BNB instead of risking XRP.
