Don't take me wrong, I'm a proud hodler myself, but I'm very aware of the risks so, if I lost all my BTC because of an unexpected event like a dump not followed by a recovery, I wouldn't be ruined. That's what we mean by "...only the amount you can afford to lose".
And if anyone tells you otherwise, he lies. tranthidung is a great poster and didn't forget to add the warning: "but it can change in the future".
BTW, congratulations for the OP.
In other words what you're saying is that we shouldn't use past halving cycles to be a guarantee that the next one will follow the same trend as them. In that case I can reason with your idealogy, because the cryptocurrency market is influenced by current crypto news and we can have an occurrence that might change the naretive of previous cycles. It is good to know the pertan of previous cycles as a guide to predict the outcome of the incoming one, but the point is that we can not depend on the precedents to make an accurate prediction of what will happen after the next halving. But one fact is clear that with the occurrence of Bitcoin being cut in half during halving, that creates scarcity, bull run will always follow, only we wouldn't know how massive and profitable it'll be.
