And those people who can afford to do that are those rich people since small time traders cannot afford to buy in every possible good position they can take. But for small traders they only really on current prices and trade it since they cannot afford to let their money slept since if there's no activity done they cannot earn good cash at his end.
To many things we can learn from here so lets focus and ignore those negative impression that cannot really help us.
Lol what? Negative impressions?
Dude, I believe you're new to trading or something?
Even small traders can diversify their money and keep it for future purchases where they can buy more for less whenever such situations like a crash arises. Lol tell me if your small trader have gone all in at $69k and sold at $16k, what would he make? A huge loss. But if he'd have bought at high for some % (let's say 25-30% because we all know that we are surely going to see a top and it's definitely going to retrace) and then decide a level like $45k and then the final purchase would be at $25k (assumptions I'm talking about), then he'd still be in some profit that'd cut his losses a little. But buying with total capital is stupid and shouldn't be done, you must have heard - never put all your eggs in one basket. I'd say that put your eggs in that basket one by one at different times and different areas and you'll be fine. Don't get offended by my words but as I understand, those who come here and think that Bitcoin is a get rich quick scheme and invest, they'll surely lose because of their mindset.
