And yeah bitcoin is volatile and it is not guaranteed to go up, yet it seems that at the same time it is amongst the best of places (if not the best of places) to be putting value for a large number of people around the world in terms of whatever that they are able to save up for a couple of cycles or longer.. then it is likely that their purchasing power is going to be better preserved by keeping the value in bitcoin as compared with any other place that it can be kept.
Of course nothing is guaranteed yet bitcoin is much more compared to every other asset, looking at the past of bitcoin and how well it has performed there is no much asset that is better than bitcoin for a long term investment even though there are other forms of investment that might be profitable yet bitcoin seems to be out performing them. Bitcoin as a store of value is one of the most underrated by low coiners or no coiners for the mere fact that it's volatile whereas it's volatile nature is one of the most adorable features that it has as it creates more opportunities for one to buy at a cheaper price.
Indeed bitcoin has out performed every other project including shitcoins. Etheruem which is known as the king of altcoins/shitprojects is gonna be a decade old by July yet it's price value is nothing compared to the price of Bitcoin when it was a decade old. There are several factors proving that there are no second best when it comes to bitcoin so I wonder why people think of diversifing their investment if not for the sake of gambling. It's true nothing is guaranteed yet people still have fortune invested in bitcoin and they still make profit from every bullish season. I know it sounds a bit strange but I can't give up my accumulation because profits aren't guaranteed, life itself is presented without bunch of choices which are all risky, it's left for you to pick which of the risk you're willing to take to make a difference.
