As we can see each and every transaction for bitcoin is publicly registered to the blockchain where in all of us have access, so I am just thinking if anonymity or providing privacy will be the next move for bitcoin. Just my thoughts, you can add yours here and let's discuss it.
actually what is always recorded is not our personal data, so we still have privacy, this also makes us unable to be deceived and makes the authorities to detect money movements improperly, things like this do not make a problem for legal business actors, so the features of bitcoin has never changed and can never be changed, because each server fills each other and protects each other's data.
Its the ingress/egress problem, so long as you never buy or spend btc, your private,
As soon as you open an exchange, or trade, then THEY (GOV) has you,
You could of course pay cash on street for BTC, but the fact is unless your 'dead men tell no tales' kind of mobster, then its a public transaction, which means witnesses, buy/sell, ... but its still public
Again, why is that everybody has been busted? WHY? because companys like PALANTIR (NSA) track all bitcoins, even the mixers can't outwit the NSA
