BTC is easier to carry, you can travel around the world with it, but gold's easier to sell, and there are more buyers. I bet there are more gold ATM than there are BTC ATM in the world. All the Chineses and Indians love gold.
Why do you think physical gold is easier to sell? Have you ever sold gold bullion in real life? You can sell bitcoins at any of the multiple exchanges out there within just a few minutes (actually, transaction confirmations would take longer than the selling process itself)...
Yes, very easy. You walk into a bank, you put your gold coins on the desk, and they give you cash straightaway. That's in lovely Switzerland. Anyone knows of a shop where you can sell
BTC for cash? It's much faster than selling
BTC online, because you have to wait 24 hours to have the money on your bank account.
