Not nonsensical. If a pool controls the 51%, it can rewrite the blocks. Look at why the price of xmr has steadily decreased since 2022. It's due to a greatly increased risk of this happening.

And the higher the hashrate is (assuming it is relatively decentralized), the more expensive a 51% attack is. This is the security factor. Bitcoin has the highest hash rate of all crypto currencies and is decentralized enough to make a 51% attack way too expensive to consider. Game theory suggests that's it's a better economic decision to buy bitcoin and lose some privacy vs than to opt for privacy and have your chain rewritten and lose all of your value.
Every PoW crypto has completely different algos. Makes no sense to simply point to pure hashrate and say that is what makes Bitcoin more secure.
Decreasing price is due to everyone being scared of that specific thing happening? Where in the world did you pull this one from
What a jump
