Martingale is a dangerous strategy when you are in to margin trading. But Crypto trading in India is done without using leverage, Martingale strategy is not so dangerous. We advise caution and warn not to use very small gap between two trades.
Martingale strategy is to double your position every time the market goes against you. For example you buy 100 coins at Rs. 21, buy 200 coins at Rs. 20, 400 coins at Rs. 19, 800 coins at Rs. 18 and close all positions when market rebounds to Rs. 19.
Risk to Reward Ratio doesn't hold good here. You are taking more risk to earn less profits. We do not recommend this strategy. Martingale strategy is very dangerous for coins where volatality is high and less dangerous for stable coins like Tether. If you want to use Martingale strategy in Tether, use a gap of minimum 50 paisa.
