Regulation is coming because it allows governments to apply taxation and traditional banking services their haircut.
The interface between conventional finance and BTC will become the battleground / choke point because they cannot stop the flow of crypto (I would include stable-coins in addition to BTC) within the system.
I understand Tax Departments in multiple jurisdictions are already advising against using mixers etc which will put them, for their purposes, on a par with other tax avoidance schemes.
Smart governments will allow the finance industry to create tax-free wrappers etc (401s, TFSAs, self-select pensions, ISA, tax exempt investments etc) dumb governments will do as dumb governments do…. either nothing or too much.
Hodlers & stackers will be fine in the long term. Apologies for the stream of consciousness.
