Bitcoin is a digital currency that has come to stay, as long as the internet stays , most persons that didn't believe in Bitcoin 10years ago regretted it, that will be also be the case for people who don't be in it now come 2034.so think positively take the risk and Investment in Bitcoin today.
Despite the positive output of Bitcoin, many people are still not yet convinced and always think it was a scam or a Ponzi Scheme. But no urge the change their mind nor I would say they will regret it because that was their views and market opinion as well. Once a person is negative, it is hard for them to change but rather stay against it.
Although Bitcoin is popular now, it is not enough to drag people's attention. It is to say that those who want to invest will invest but those who are not are free to leave negative comments.
