True. The cheap and speed aspect of other altcoins are very useful(despite a lot of them not being designed for payments specifically) for quick transfers at least for now temporarily, until we get a widely used Layer-2 solution on Bitcoin.
Yes, Bitcoin has a widely used Layer 2 solution!
I know you are familiar with Lightning Network (a secondary layer to the Bitcoin blockchain), El Salvadorians used that network for faster and cheaper transactions involving Bitcoin in the Chivo app. Not only the El Salvadorians using the Lightning Network but also Cash App and Paxful.
