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.
Well i think we won't becoming excessively dependent on computers to manage money and whole assets, because many people or developers whom make bitcoins becoming more easy on smartphone.
But I am more a bit scared we will be depend on the smartphone. While use bitcoin or related with cryptocurrency activity.
