There was a perception about the increase in the price of Bitcoin a few years ago. I think that the price has increased much faster than it has come to this day.
I think that those who invested some money in Bitcoin a few years ago have exceeded their investment expectations today.
Bitcoin investment does not guarantee any profit. Even if you hold it for a long time, there is no guarantee that you will make guaranteed profit, similarly there is no way to say that you will face a loss. However, if you can hold Bitcoin for a long time according to your ability, then you can definitely build a large Bitcoin portfolio that can help you become profitable in the long run. The price of Bitcoin has changed drastically in the past few years. This will continue in the future as well. But those who do not accumulate their Bitcoins after a long time may be the ones who may lose. If you have excess money after making necessary expenses, then investing in Bitcoin can be safer than any other platform.
Your statement is very confusing the reason why I'm saying so is because in your first sentence you said Bitcoin investment does not guarantee any profit even if you hold it for a long time and you said again that if you can hold Bitcoin for a long time according to your ability, then one can definitely build a large Bitcoin portfolio that can help you become profitable in the long run, so basically you are saying accumulating and holding Bitcoin for long term those not guarantee a profit and again saying it those guarantees so basically you are confusing your self, the only way Bitcoin investment won't guarantee profit for long term holders is when it stop growing in price and value, and with the way Bitcoin is going it will keep growing because is already becoming more valuable, some countries has already created a Bitcoin reserve and more state are proposing for such, Yes no one is too sure about the future of Bitcoin and anything can happen in the future but with the way things are happening around Bitcoin one can say that Bitcoin has a great future.
Lastly you must not have excess discretionary income before starting your accumulation any discretionary income available can be used.
