Don't see bitcoin as mighty like you (yet), it's a different system that indeed has several advantages. But i still consider gold better.
For now on bitcoin is not yet special to all people but to those who knows it only, what I mean is you consider gold as better now than bitcoin because bitcoin are not yet already expose to everybody but the thing is when the bitcoin already expose and known to everyone then I probably say that bitcoin is better than gold. However, Bitcoin is money not an investment. Bitcoin are only digital coin but it is already consider as money that can be converted into cash.
