1. I can send Bitcoin anytime anywhere as long as I still connected with the Internet,
I can do that to fiats, what is the difference on the BTC than on FIAT? I guess the transaction time and the transaction fee.
2. You can make money with Bitcoin, because of the price of Bitcoin always changing,
The price of Fiats to other Fiats are also changing but not as quick or fast as Digital currencies. Bitcoin is a decentralized cryptocurrency the reason it is so volatile.
3. Bitcoin can be accepted around the world because every people already know Bitcoin,
Really? I don't think so. There are a lot of countries that is not allowing the regulation of Bitcoin, they banned Bitcoin in their countries so I don't think it is accepted around the world.
In terms of the Fiat, this is true though you still need to go to their Banks to convert your Money into their Fiat.
4. You can send a lot of money to somewhere with Bitcoin.
The reason why a lot of government are afraid of people that might take advantage of Bitcoin's decentralization and anonymity. They can commit money laundering or even have a transaction to criminals using this.
