Getting Bitcoin onto lightning won't…
Getting Bitcoin onto lightning won't be hard. Once people want to spend it. There will come a point when the price of Bitcoin is about twice the total global wealth. Half in circulation and half in cold storage. At this point if more is held, prices will increase and you would have a better than 50% chance of selling for more than average price. That will ensure that sufficient Bitcoin gets into circulation.
My napkin calculation is that that is about 50,000,000 per Bitcoin, allowing for some lost coins or about 50c per sat.
