In the physical world, GOLD is the real thing. Every fiat currency is linked to it. This is the digital age, which is at its beginning and it's going to be the future. Bitcoin was the first cryptocurrency, with a low circulating supply of 21 million, Satoshi Nakamoto designed the crypto almost perfectly. But he would have never expected Bitcoin to rise like this, he just wanted to try out online transactions without a middleman, his algorithm wasn't meant to be used for mass scale adoption, which is the reason why it has a slow transaction speed. Bitcoin will reach epic heights in the future when it gets more mainstream adoption. Its status as a cryptocurrency is getting deteriorated day by day, and its status as the digital gold is rising day by day. We might not use Bitcoins for transactions anymore, but it will never go away! It will always be the first, it will be a legendary currency to the future generation.
