I do not know what makes this bitcoin special compared to other currencies and commodities, whatever makes people interested in investing here, obviously this bitcoin is very special what makes it special that's what makes special bitcoin.
you are right bitcoin is much better than other currency because of some main reasons, bitcoin is one of the most secure and popular,
bitcoin price now reaches to $16,000 and no other currency reaches to that level and also people get effected only because of the price thats why bitcoin is much special than other currencies.
It did even reach out its ATH of 20k usd on its price and no other altcoins did able to reach such heights and this is normal and what makes bitcoin special because we do all know this thing is the king of crypto. One of a kind since this is the first coin did lunch into the market and been adopted by big community which causes of its price to rise its price on the ranges that we do least expected.
