It has nothing to do with the issue rate of Bitcoin, frisbee-on-the-roof is potentially a real problem.
Say Bitcoin crashes down to $1 tomorrow, such that it's no longer profitable to mine. A bunch of miners go dark. What happens to the block time?
Now remember that difficulty readjusts every 2016 blocks. If there are now 1% as many miners, that means a 1000-minute blocktime and potentially up to 1400 days per adjustment period (average of 700).
In this situation, the only option would be a hardfork to bootstrap the network back to a live state, either by directly adjusting the difficulty or by readjusting more frequently and more aggressively.
Are you saying this will happen to all crypto or just Bitcoin? Ok if Bitcoin goes away, it might over time, exponential decay and what not. Or might also go up. But crypto overall will most likely go up. Like you can't go back.
And I feel like people for example aren't talking about the fact that technology doesn't really go away. Like any technology we've ever invented is still used somewhere. This will very much be like bitcoin.
