Me stupido sold at approximately $37.400 in order to buy again at a lower price. Well, let's just say that didn't really go according to plan. I'm planning to buy back the exact amount I sold, if the price ever falls back to that level.
Yah, I've done that, and learned the hard way. Bitcoin price swings are just so unpredictable and can go either direction. And it can go hard some times, like to day.
I now just buy and never sell. I buy more on dips. Don't trade.
So, I bought when it hit 38k (then it went 41k, and then fell), and so I bought more at 33k, and at 31k, and at 44k now. Hehe you get the picture.
