We have and are still trying to own it because Bitcoin is a currency that cannot be controlled by third parties. Wanting to use Bitcoin as a means of payment can be done easily. It can also be used as an investment asset.
With Bitcoin we get freedom because 21 million Bitcoins were created for everyone from various backgrounds.
Unfortunately, of the billions of people on this planet, there are still those who do not or are against this freedom.
No one needs to convince anyone to get involve in this market. It is the prerogative of the user if he will buy some or not. Some are hesitant because they are not familiar how crypto works. It is not that they don't believe, but a lot don't know how to transact with crypto yet. So at the end of the day, it is up to the user if he will own some crypto or not. This is the good thing about this market, no one is oblige to take part in this market.
Bitcoin is never an easy investment. Its highly risky and if you are not responsible enough to secure your investment, you might end up losing all your coins in just a blink of an eye. Probably the reason why this makes very hard for regular investors to risk their funds with bitcoin. No one will be responsible of your own investment, so at least you should be highly knowledgeable about bitcoin at first before you decide to buy and hold bitcoin for long term investment.
