I am also a bit scared about the possibility of becoming excessively dependent on our computers to manage our money and whole assets.
If these days when the bitcoin is worth $900, we are permanently facing continuous menaces of hackers and scammers to take our coins, I don't know what we could expect in the hypothetic scenario when the price of bitcoin arrives to $100,000 or one million dollars.
How the Bitcoin price increases like that, the problems also increase and hackers and scammers also increase. So the users must take for their coins. If the price is increased to 1 million, the dollar then I think our government will ban this cryptocurrency permanently because they will not get any income from this cryptocurrency.
