Can the strategy used to trade forex also applicable to trading crypto ?
Yes. But the problem is Crypto doesn't have much history compared to the forex. So the movements are not much predictable. When we take a look at forex charts you will see historical data for at least 5-10 years back. But when downloaded you will see historical data for at least 10-20 years. But in crypto most coins don't have that much historical data. There for support and resistance levels are not much stronger like in forex.
