Sitting on the gear to attack later is just not good business.

That makes sense, however the incentives may still be there, some might want to increase the 21 million cap so they can still mine, some might do it for the sake of it, we don't know what reasons anyone will have, we just know that attacks on the blockchain might be fairly easy and don't cost much, and that itself is an issue.

however , as far is economic is concerned, your theory is valid , if bitcoin is worth so little that it becomes easy to attack , it won't be worth the attack in the first place, economically it makes no sense.

The biggest issue would be a pool or group of pools that gains enough hash. But I would think the same backlash that hit ghash.io back in the day would happen again.

That's another major concern as well, very well addressed by you.

Edit: As for the blockchain size, I really think that is a non issue. I just got a 1TB SSD for under $100 at Amazon. I could have gotten it for less but I was in a hurry and just wanted to get it ordered, did not want to stop and shop to save $10.00.

100$ is a lot of money to most people , as far as using it to store a blockhain that doesn't pay you anything, those who would always need to run nodes regardless of the cost would be mining pools and businesses receiving payments on the blockchain, at that point , most pools will close down , if price doesn't "moon" many individuals will lose hope and simply shutdown their nodes , this takes us back to your statement:

It's all really going to depend on the price...

everything goes down to that, decentralization of nodes , decentralization of mining , security and adoption will always depend on bitcoin to be worth a minimum price of x number, this puts us in a very difficult race against time.

But as I said earlier ;

I personally think that before 2045's halving whereby price only needs to be at around half a million $ per coin is somehow safe, after that things will start to get really difficult...

if the fiat system collapses by then and bitcoin does become a real mean of payment which is attached to no fiat value, we won't have to worry about any of this. Roll Eyes
