Bitcoin holders believe in bitcoin's ability to act an an anti-inflationary agent in their portfolio. If Banks are the disease then bitcoin is the cure! Bitcoin is going to prove to be the greatest safe haven asset the world has ever seen, & it is currently already doing quite a fantastic job at moving up in price over time & the chart looks absolutely beautiful. I plan to hold on for at least another 5 or 6 years I think around 2030 the crypto market will be very mature.
IMO, there is no safe haven asset. Bitcoin investment also has risks, the price also fluctuates and unpredictable. I don't really understand why you think Bitcoin is anti-inflationary, I think the assumption is too exaggerated. I also disagree if you assume bank is like a disease. In a certain situation, bank also helps us to have a proper financial system. Sure, Bitcoin makes us to have a better financial in the future. But we can't discredit the existing financial system.
It is good that you plan to hold for 5-6 years. However, you need to understand the 4 years cycle of bearish-bullish. You don't choose the wrong time for buying a lot of Bitcoin for you assets. The bearish season is the best time for buying, meanwhile the bullrun season is the time for taking profits. Personally, I don't set certain years for holding, I just adjust the 4 years cycle. I think it is the most effective way to determine the goal/target.
