true. i wonder on which of them it's the most difficult to gain majority. It looks to me like POS is the most difficult.
Considering how users tend to keep funds at centralized companies (and the big historical heists), and how asic mining centralized I think crypto "security" is highly overrated.
I think the real security comes from the normally OSS nature of these projects (eg, the network can be forked or split if a significant attack happens, like with the BSCore take-over).
