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.
I think that we should only invest shortly at this point, you can see that the market is still fluctuating and difficult to predict, bitcoin prices are constantly fluctuating and greatly reduced over the past 7 months. Regardless of the past few days you may find that bitcoin prices are rising slightly but may continue to drop sharply at any time. Therefore, I believe you should only invest in short bitcoin.
