Sweet gig if you can swing it.

But you're really shooting yourself in the foot with this all-or-nothing attitude.
The optimal solution is always going to be measured risks and hedges.
To quote my example in the OP: if Amazon steals my $5000 it's not a big deal.
In fact by the time they've stolen it I may have already earned/saved more than $5000 using this strategy.

But then you seem to go completely off the rails and say you're never going to use LN or DEX.
Why is that?
If you run the LN node nobody can steal from you; that's the entire point.
A DEX isn't going to steal your money either, and if they did the window of opportunity and total amount is tiny.

I must admit that your on-chain transaction history is quite impressive.
I thought I'd easily find evidence of bullshitting.
That doesn't seem to be the case.
