If Facebooks Stablecoin launched under Trump 2.0 it would most likely be bigger than Tether. Tempo is yet to be seen. I mean other big banks will probably want to launch their own or simply change their banking model.

Meanwhile Bitcoin will still be there finding blocks, and bitcoiners will hopefully educating newbies on how to use it.
