Yes, in fact, every day the largest user of money is Fiat, and I think the percentage of Fiat usage is higher than gold and bitcoin.
You
think that the percentage of fiat usage is higher than gold and bitcoin? Of course it is higher. You are basically talking about all of the nations' currencies together, versus gold and bitcoin. What other option was it going to be?
If you want to pursue a profit percentage then Bitcoin is the right choice, but if someone wants a safe investment then gold is the choice.
The profit percentage for the two is different because bitcoin is speculative so it can provide large profits in certain periods. Gold does not have advantages in this regard because gold tends to be stable.
Keep in mind that as Bitcoin gets more adoption the speculation will become less and less. But we are a long way from that.
