Recently, some of the Governments which has completely or even marginally regulated Bitcoins, emphasis on the KYC of the BITCOIN ADDRESS. Although, it is necessary for the Government to avoid fraud and money laundering at the most basic level, it exposes the wealth of the holder in an adverse way. Not only the employees and receivers but also unknown personnel who might view the wealth of Mr. XYZ here...
Now all it takes is a knife or even a makeshift gun to leave Mr. XYZ penniless, in this case #bitless.
A unified transparent ledger. The most important aspect is, that it is losing its anonymity. Bitcoin will not be anonymous anymore, hence should we trust coins like Dash, Zcash and Monero more?
What will happen to the Bitcoin market in such a catostrophic event. WAKE UP! YOU THINK TOO MUCH...
Although as a cryptocurrency enthusiast I always recommend wallets like BTC.com which offer multiple addresses to maintain anonymity, I am not sure how far this will be accepted by the "Governments"
