Bitcoin is referred to as a digital GOLD because of its value. But for me, bitcoin is a digital currency. We used bitcoin to promote the fastest way or method of transaction as possible. Besides, bitcoin has surpassed the value of digital gold either or it is an asset that can be used as an online payment transaction these days. Technically speaking,we cannot know the cap of gold so we can't really compare it to bitcoin.
Well, in terms of value, BTC does surpass gold, but that's not the main benchmark. By analogy, bitcoin is indeed suitable to be called digital gold, its price is high and so valuable compared to other products. In addition, there are limited numbers and must be mined with certain difficulties to get it. As it seems.
Bitcoin is also more multi-functional, it can be an investment asset, trading commodity, and currency for payment alternatives.
