When you are selling it , you are indirectly participating in the dumping process.
Wrong. When you are selling Bitcoin you are
directly participating in the dumping process.
It's hard to say what's going to happen. But if you are bullish on Bitcoin long term you should be buying more on sale (if you are able to). If you are bearish in Bitcoin long term then you should sell. And if you are just following the leader, you'll never make any money and should get out of all crypto currency investing.
Too late I panic sold (took profit) when bitcoins fell back down to $18k and will let the price hit the bottom, wait for a
$1000 rise and then I might buy back in again.
Cool hard logic tends to beat faith driven buying/selling every time.
Ah, speaking of logic, so you've already bought back in? We hit (at the time) what would been considered a bottom at $8,000 last week, then we crept back up to $9,000. That would have been the floor + a $1,000 bounce...so according to your decision logic that would have been the time you were going to buy back in.
Are you bought back in?
If not, you have no decision logic, you're just watching the roller coaster from the sidewalk, standing at the "line starts here" sign, unsure of what to do next. Good for you on getting out at $18,000. If you support bitcoin long-term, now is the time to start doubling your stake by getting back in.
