I've checked a number of factoid slots and found some points that might find interesting to discuss with you.
I'd like to discuss some of the points I quote below about the future of bitcoin, and I'd really like to know if you're worried about that?
2. "I'm sure that in 20 years there will either be very large transaction volume or no volume." -- Satoshi
About the second point: It is possible that there was no transaction volume in bitcoin's first 20 years. However I wouldn't worry too much about that because up to now the volume of bitcoin has been huge and bitcoin has dominated the market for a long time.
Then, what do you think about the two points above.
There is a secondary network now, so off-chain transactions don't happen on public bitcoin.
