I agree that “level of security” is a crucial criteria to determine the #crypto in which you want to keep your capital. I don’t doubt that #Bitcoin is a more secure choice in terms of hashpower although I’m not sure how we can really compare it with #Monero which uses RandomX. It’s possible that Monero hashpower is more decentralized than Bitcoin hashpower. On the other hand, it would certainly take less capital to attack Monero but Monero could be easier to defend since everybody has a CPU at home.
Regarding long-term security, while Monero security budget is ensured by the tail emission, there is still a lot of question marks on how Bitcoin miners profitability will be provided in the future.
Finally, privacy is a component of security as well. The fungibility of your Bitcoin funds can be more easily attacked by governments through #KYC requirements like those being deployed through the #TravelRule.
Although, this question would need to be looked at more closely, I’m not convinced that your funds are absolutely more secure with Bitcoin than there are with Monero. Both have pros and cons on this matter.
