When you start trading using bollinger lines you will see very interesting movements, for instance here, the bands appeared last on the 1H chart. Whenever it hits the top band it's a "sell signal" or it's interpreted that way by most bots, these bots start selling as soon as the next 1H candle appears. Then folks start to panic, they begin to sell without really understanding why and we sometimes (or very often with memecoins) have a chain reaction, a fire sale. Most folks have no idea what's going on and they are like a bunch of sheeps following the lead. But if you're a keen observer, and if you've done your homework, you know by now that bollinger bands alone are meaningless, you have to combine them with RSI or other indicators, in the case of the coin i'm showing the RSI level is super low, there's no "top". That doesn't mean it'll pump super high at all but, potential is still there. You can observe memecoins without having to buy them anyway, you'll learn a lot of interesting stuffs about human psychology, fear and greed.
