First of all congratulations for your 80% profits which you have already made. I've some questions if you don't mind:
1. How do you exactly analyse the Bollinger bands as an indicator? Any guides available?
2. Do you use Stop loss?
3. Is USDT your main pair?
1. 80% of the time markets do not have a real trend and they move between the upper and lower Bollinger band. So you will notice a lot that the price is waving between those bands. as soon it touches the lower band it will wave back up until the middle line or upper Bollinger and then reverse back down. So I 80% of the cases after a candle touches the lowest band the price will move back up. It is a very accurate strategy but not a 100% guaranteed.
For example if bollingers are squeezing together and the candle breaks down the lower band then its very likely we get a major dip that wil go way below the bollinger. So when I see a squeeze and the candles go down then I wait to enter the market cause likely it will go down further.
But for the strategy you will notice that in 80% of the cases price bumps back up as soon as it touches the lower band or breaks it with a 'flash crash'. So it is a very good tool to make some profits. You will not make huge profits but profits between 0.5 and 2% can be made easily by using this strategy.
2. In this strategy I do not use stop loss. In this strategy it is important to not use your entire balance in 1 position. Cause you never know. If you buy a dip that breaks the bollinger but the market decides to keep dropping then you must have some balance left to buy extra. Stupid example.
I buy 5 XXX coin @ 1$ per coin for a total of 5$ but price keep dropping
Then I buy 10 XXX coin @ 0.9$ for a total of 9$ but again it keeps dropping
Then I buy 10 XXX coin @ 0.8$ for a total of 8$
So now I have 25 coins for a total of 22$ which means my average buy price is 0.88$ which mean I will start making profit of price goes back higher than 0.88$ even on the coins that I bought at 1$. Lets say price goes back up to 0.93$. Then you almost make 5% profits even on the coins you bought at 1$ cause you decreased the break even point by purchasing more coins.
3. In this challenge my goal is to increase my USDT value. So yes in this challenge USDT is my base currency. So at the end of a trading day I will have USDT in my balance and no crypto. But this strategy can also be applied if you want to increase your crypto value
