Do we really think that the btc network is going to be able to handle the future transactions in bulk and speed even with lightning network ?
If you are just asking for a personal opinion then I think yes. BTC would still be able to cover the network. As long as mass adoption would take place and no FUD's are fighting BTC. Since most exchanges and fiat tradings are pretty clogged in transactions right now. Also I think we are having difficulties with transactions speed today is because of the removal of the China mining farms. But once we have mining farms again who can cover all the transactions then were good to go again.
