I think it's not just about the timing, but also about how much profit you can get after you buy at this time. Because there are many people who get profits through their investments even though they haven't even reached five years, so this is not only about time, but also about how much profit and how much you can hold when you see the profit in your own wallet. But if you buy Bitcoin at this time not just for investment, maybe the story will be a little different from investors who only aim for profits through Bitcoin.
Time and profits the key words that dominated your submission are for those not planning to hold for long and that is at variance with the title of the thread. The thread is more of building a Bitcoin portfolio and the various suggestions and discussion are focused on effective ways of doing this.
To realise quick profit in Bitcoin, one can be so lucky to buy today and the next day the price rise giving unimaginable profits. The reverse can also be the case and the result could be a huge loss. In reality, this is pure gambling which can be avoided by simply adopting the long term perspective.
I still feel that long term approach give bigger profits in addition to less stress. Those bought Bitcoin early part of the year and refused to sell might have seen good profits now far more than those who sold when the bull run started. Those they will hold into next year following the halving might even see more.
