First, never get too attached to any currency or project. Profit is your ultimate goal.
The market is down now, as most are skeptical about announcements regarding Bitcoin ETF.
If the news is a possitive one, it would have a possitive effect on the market.
Day/arbitrage trading is also a way to make profits. You'd need to educate yourself before venturing in.
I agree completely. An early mistake I (and I'm sure many others) have made is to add emotion to the equation. Sure, invest in like 1 or 2 projects you are passionate about and believe in no matter the price, but for any you aren't completely ride or die for, set an acceptable loss percentage and move on.
