Looking for a way to optimize my strategy

[GerbertPhills]

Looking for a way to optimize my strategy: 
 
Currently buying BTCUSDT at a certain price and selling it at +2% on a daily basis. 
NEVER SELLING AT LOSS. Always waiting for it to reach the buy price + 2%.  
 
I was doing it for a while with good profits, but couple of time I got stuck for a long time because I was holding it till it reached my +2%. So this time I divided the budget into 10 steps, so that if it doesn't reach my +2% for a while I can activate the next step when BTC drops to a certain price and keep doing my +2%. 
 
The division is based on the BTCUSDT, 5000 per step: 
 
Step1: Buy when 1BTC = 60,000USDT 
Step2: Buy when 1BTC = 55,000USDT 
Step3: Buy when 1BTC = 50,000USDT 
And etc. 
In total 10 steps. 
I personally don't believe that it will ever reach lower than my 10th step, so that's ok for me. 
 
Would love to hear from people who do similar strategies (1. Never sell at loss, 2. Divided the budget), how they decide on their buy signal and how they divided their steps. I feel like my entry points are quite random and could be optimized.
