How we can determine BTC is digital gold?BTC Thats can be determined by their attribute. Gold is valuable because it's rare and has a limited supply. This term is true for Bitcoin as well. Both can be exchangeable with essential goods and they are acceptable in our society. Gold and BTC both can be stored though they have different methods to do that. But if you compare these criteria then we can say Bitcoin is digital gold.
I agree that they both have the same nature. although the difference is no less important. where the price of gold is much more stable than bitcoin. then in terms of market demand, Gold is more diverse than Bitcoin. The reason is, there are only two uses of Bitcoin, namely for payment instruments and investment assets (speculation). Gold is actually more than just an industrial sector, both jewelry and electronic devices. then in terms of manufacture, bitcoin is made using computers and software, while gold itself is a natural resource.
