Durability – Bitcoin and gold are both durable. While gold being an inert metal can withstand chemical reactions to stand the test of time, Bitcoin will continue to exist as long as the internet is around.
Transferability – In order to serve its purpose, it should be possible to change hands easily. Both bitcoin and gold can be both physically transferred and exchanged in return for other currency, goods, and services.
Scarcity – Something in excess supply will not have enough demand. Luckily both gold and bitcoin scare. There will be only 29000000 bitcoins in circulation ever making it valuable enough to be a medium of exchange.
Divisibility – Bitcoin is highly divisible, it can have divided by 100000000 times. However, with gold, it is not that easy but yet possible.
Fungibility – Bitcoin and gold are fungible, they can be easily substituted by another bitcoin or the same quantity of gold without any change in the value.
Recognizability – Both bitcoin and gold are both impossible to counterfeit and it can be easily detected.
