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 a little bit confusing because your first sentence says that bitcoin doesn't guarantee profit even if you hold it for a long period of time which is wrong by the way, but normally in bitcoin returns are not guaranteed, because it is volatile in nature, just as you make money when the price goes up, you can also loose money when the price goes down, but to be on the safer side just buy your bitcoin and hold for long period of time, because there is no investment without a risk.
Well everything should be corrected according to its nature and everything doesn't have guarantee since risk is always their knowing how volatile Bitcoin is. But people should not get afraid with it since if they focus for long term and make the historical data as guide of their investment then they can provably figure out that there's more good chance to earn on Bitcoin if they hold it for long term rather than thinking about short term trades with this coin.
People would really be on best side if they choose to HODL since they provably could avoid thinking to much the negativity on ongoing market collapsed and could focus on better side then accumulate more volume which provably rewarding for them in future.
