After reading a lot of posts made by people on this forum, I realized about 75% of them see Bitcoin as a digital Gold. For me, I don't think Bitcoin is a digital gold. Cryptocurrency or Bitcoin to be precise, was developed to be a safer option for transaction of goods and services and also the best mode of payment. Bitcoin was introduced to disable all the restrictions that banks and the financial system presented. A lot of people have lost huge sums of money because they saw bitcoin as a digital gold. I know others will argue that bitcoin has also made people rich but for me, I don't think it is advisable to consider Bitcoin as a digital gold. Bitcoin is a digital currency.
You're right that Bitcoin is physically nothing like Gold. Precious metals are near useless for trade and payments, so in respect to BTC, it is more like cash and debit cards, as it's a relatively easy method of payment. For example Bitcoin is more accepted by vendors and markets than Gold at the moment, in this respect it's closer to a payment system like visa. The idea of Bitcoin being digital gold is more related to the idea of both being commodities, and therefore having lower inflation, with Bitcoin in particular having a fixed supply and controlled inflation. The context is more that it is "a digital gold", conceptually speaking, as a store of value. With the idea that it will increase in value like Gold has over the decades and centuries.
Hope that helps to explain things. Personally I don't see it as a digital gold, but rather "a new gold". It can be easily compared to a precious metal or form of fiat currency, but it will always be unique with it's controlled inflation, fixed supply and decentralized network.
