"But in reality how many existing retail holders even want to buy more up here?"

I'm one.

"it makes no sense to average up at a >150% premium to my cost" is like saying you'd never buy another share in anything.

Cost is relative to risk and your financial position at any one time.

Imagine you bought Apple for $1/share using the $10K you had.

When you have another $10K you want to invest you have to decide the best place to put it. That could very easily be more Apple for $30/share

They are now worth $170USD

Pretty good outcome.

So if you think CU6 was going to trade at $8 mid year it would very likely be a better investment than nearly anything else despite having paid $0.8 for your first foray.
