You do have a point about the difference of the two. But it seems that bitcoin is for us. We are here to earn since we do not have any money to buy for gold. Gold is dangerous to have since people knew its value. Bitcoin like what you have said can be eatned that is why bitcoin is for us.
Gold is going to put your life into the burial if you are not going to be careful with it. Because a lot of eyes are going to be pointed to you.
As they know that gold is really going to be a good way to have big money so they are going to do everything just to get it to you.
And it can also make your life in danger, so it is better to use bitcoin.
