If someone had told you during 2015 that Bitcoin will exceed over $100k one day and you should invest in it as at then. Would you have believed?
Bitcoin was not so rich in 2015 that we could believe such big predictions about Bitcoin back then. There are still many people who would not believe it if I told them that Bitcoin would reach 1 million or more. You may even be one of them. You may admit to believing in words but if you are asked to take risks with money, you will express doubts. Predictions are always uncertain, some will believe or some will not. But when it comes to calculating the profit and loss, most will express doubts and refuse to believe the prediction.
Never regret the time that has passed. Rather, learn from the mistakes of the past and try to make the present time flawless so that you do not have to regret it in the future like the present time. There is still time to invest in Bitcoin and profit from Bitcoin. For this, you need to be able to take risks and patiently hold Bitcoin for the long term.
