In crypto you never look at trading indicators. Trust me. Market is so volatile you'll never knew when it will going to down and up. Even Machine learning bots for speculating Market movements are useless. In Crypto, your trading indicators would be luck, news, shill and FUD.
if we look at trading charts in the past, we will see repeating patterns, although there are no indicators that are 100% accurate but at least it helps, when the market is stable or the trend is the use of indicators is very helpful..
RSI and Bollinger bands were commonly used indicator as far as I know but not having much belief on the trading indicators unless we have intention to trade,intra day trading.If we can able to hold the funds into longer term trading then fundamentals would be enough to sustain in the market.
I don't really like the RSI indicator and rarely use it, but for Bollinger bands I always use it to determine price ranges and market conditions, so Bollinger band is not the main indicator but must be combined with other indicators.
