Normally every strategy would have a Risk-Reward ratio of 1:1. To create a low-risk strategy in every trade try to take this ratio to 1:2. 1 times risk for two times the reward. Other than that one good strategy that doesn't always work is buying 24h lows. You just pick the 24h lows from Binance see if the low is backed by a big red candle on the chart and wait for a retracement in an upward direction.
Yes, it’s not advisable to buy when they are just getting into the market, because you’re sure heading for a loss. It’ has become a normal thing for people who are holding tokens to sell them immediately the token lands the market, and that would usually affect the price in that first time it is starting, they all end up crashing to a lower price than what they got into the market with, and if the project is strong they are still going to recover after the drop, but that’s not usually the case for all of them.
I like the strategy you have here, it’s a good strategy and is definitely going to work if one follows it right.
