What if 4 years cycle is not here this time.
What approach one should get here.
Thanks
If the 4-year circle doesn't work again, you go for 8 years, or you can go for 12 years as long as you can hold until you have enough profit that you could be comfortable with and decide to sell.
I don't see any other approach that I can suggest; every other approach will be risky, as it will require you to either trade your coin, rebuy, use some reputable exchange holding offer, etc. They might be more profitable than holding for a long circle, but nothing is safer than having total control over your coins.
You have given the best advice so far because i don't know why even at this point that bitcoin is performing excellently, some people still trade their bitcoins for short term profits and wait for a DIP to happen for them to buy back again. They have not even considered a situation whereby they sell at high prices and the price doesn't DIP in the short term that means it will be difficult for them to buy back. Bitcoin investment requires enough patience and frequent accumulation before one can get a sizable portfolio that can attract huge profits so if anyone don't have a long-term target of holding bitcoin, they should forget about buying it in the first place and instead gamble with other altcoins which are very risky due to their high volatility. 4 years is just a cycle and i don't think it can be seen as a long time for one's investment to mature so the target should be between two to three cycles just as you stated.
