So how vulnerable are we, the hodlers, today, to another threat like this?
Discussion
Depends what you define as “threat”. What are you worried about?
The hodlers don’t have any power and never did is basically what I’m saying. You are at the whims of what these other groups feel is most important to them. One of those things might be your loyalty and usage of their products, so their reputation in the “hodlers” eyes matters to a certain degree. But if you aren’t even using their systems and off in the woods somewhere by yourself with your node not transacting then they don’t need to care about you and neither does the system.
