Well, I think that is a good strategy to prevent the big loss, especially if the price goes down deeper. You can use that as much as you want, but you should remember that you still pay the fee, which will become bigger if you trade mostly.
My goal was to wait for the bitcoin to increase then buy for example at $5300 and at the same time place a stop limit at $5300 and to sell at the first red candle.
In the best case I earn a profit and in the worst case I pay the transaction costs.
What do you think ?
Then you should be patient for a while to wait for bitcoin price to go down. We don't know when bitcoin can go down, and what price bitcoin will reach in the bottom because until now, bitcoin is still trying to increase. You can place an order at the lower price, for example, $5,300, and you can set the alarm in $5,200, so when the price reaches that, it will sound, and you can decide to let the order will fill or change in the other lower price.
Do you know of exchange platforms with 0% transaction fees?
I think all exchanges have a fee for every transaction, and the amount will be different. But you can pay a small fee in Binance by using the Binance coin.
