i buyed 500 binance coin at 2,5$ and sell at 3,8 usd then it up to 6-7 usd, i can't buy 500 bnb anymore, then price up to 8-9 usd and more.
Just be patient and wait for another drop to buy low. If you don't want to wait, buy now and go for a long-term strategy and hold your coins, you'll make some decent profits in the long run.
Buyed 0.5 btc at 6k and sell at 8k. then i can't buy back when price up to 10-12-15-19k.
If you sold during the last rally, you can simply buy back right now, current price is around 6700, why would you wait for the price to go up to the 5-digit level? buy now or wait for another dip if your exit point is around the 8k's.
