I'd recommend one of the 3 strategies listed in the post below. They're meant to be used on forex, but they work just the same on Crypto. The second one, "pin bar reversal" is probably the best, as that gets you into trades right before big reversals begin and is compatible with day trading and swing trading. The others work well too, but they're more focused on long term trades, so are a better fit if you want to take a more passive, long term approach to trading.

Just my two cents.
