maybe for beginners bitcoin is a new investment, but this does not apply to miners who have been in the crypto world for so long, because we can say bitcoin investment has almost reached 10 years and that time is not a short time, but we should admit that this investment has only become so popular among the general public in recent years
Exactly, it's technically to some people but not for other people. But in literal sense though, bitcoin's too old to be called a new investment since it's been a decade or so of existence. It had been known by many people in the early years but the only problem is that at that time, it was all negativity for bitcoin.
