i`M really annoyed of this fungibility problem that bitcoin has, we should resolve this fast or bitcoin can become an instrument of tyrrany in the future.
It is what is is. Bitcoin is first generation blockchain ledger technology that both by design and by culture and precedent is highly resistant to change. Maybe that will be good enough to maintain its lead in the market or maybe not.
One thing we can be almost certain will not happen is that it won't be resolved fast.
it will never be resolved, if it's this difficult to make the blocksize 2MB, then unlinkability or unraceability will never be added. it's too big of a change.
