The GOVs just have to put in jail few exchangers as they did, implement the financial laws which are very strict and BTC's value will go to zero.
BTC and any other Altcoins were designed to be decentralized and free of any restrictions. Now, you have to give your DNA to exchangers when you want to cash in or cash out BTC. They report to you to your tax authorities, they have access to your personal details.
So, why would BTC prevail when there are already debit cards? they make possible instant transactions and you have to provide the same documents even less. The banks require only and ID when you open the account with them. The exchangers are are asking many other proofs.
It is so funny when I see people happy that Gemeni, Coinbase and others got financial licences. What's the difference between a normal financial company(like a traditional forex) and them? NONE.
A while ago. many of these people screamed that they want freedom, no control, decentralization and now, they applaud the opposite.
BTC is just an e-currency with a big support from media because it's a paid advertising; and it will always be like that until its value will be zero(not so far this moment).
Why would you use Bitcoin and not the fiat currencies while Bitcoin is like a centralized system?
I can use my credit/debit card to make purchase instantly everywhere with zero fees. What's the BTC advantage as e-currency? NONE.
You can only use it to take advantage of its volatility.
