My 2 sats @navrock1 is that "taking profits" on Bitcoin is very risky. Or, more accurately, misunderstands the point.
Ultimately, it's either a niche curiosity or a foundational layer of global finance. Or, perhaps, it just plateaus after absorbing a decent fraction of gold's market cap.
If it's the first option, there's probably limited upside from here long term, and all you can hope is to speculate on the volatility. Ie. A mugs game.
If it's one of the other two options, it's at least a 5-10x in the coming decades or so. Maybe 100x in time. In which case, taking profits at anything under US$500k/coin is something you'll likely regret.
Framed differently, if you think of it as a superior monetary asset, switching back to an inferior alternative makes no sense. Eg. No one in Argentina buys USD with the intention of taking profits as the peso is further debased. It's a one way door, as no sane person ever switches from USD to Argentinian pesos for investment reasons.
You don't buy Bitcoin to make money. It is money. And it's only worth exchanging your AUD for if you think it will better preserve (and, indeed, grow) your purchasing power. Which it will *if* adoption continues to grow and achieve a much higher level of penetration.
So that's the thing you need to form a view on. If you think we are on a path to mass adoption (albeit in a messy, volatile and gradual manner), buy and hold.
If you don't, it's only a speculative play thing and probably best ignored.
There are so many stories of people "taking profits" as this thing has grinded it's way from US$1 to US$100,000, and none of them good (even if it seemed that way for a short time).
Anyway, sorry for the ramble. It's a weird thing, and requires a totally different framing than you'd use for a stock or property etc.
