When big boys enter the picture, the rule has changed. Bitcoin then becoming a fprm of investments, and no longer the original vision of satoshi, iguess its really inevitable, specially during the 2016-2017 when it peaked at around$20,000. It become a speculative asset, and others tske that as a opportunity, trying to make quick bucks, or even putting thier whole life-savings hoping to become rich.
And that's also the reason why many new crypto investors lost their money when they rush to buy and hoping to ride the tide of Bitcoin bullrun last 2017 but what happen was an opposite to what they expect market correction fall to it's low of almost 5.8k$ for Bitcoin price and this really hurt for those who bought when it was at 20k$ level.
