While on paper the two might seem very similar they are in fact not actually so similar. Technical analysis is a great tool to help us trade financial securities, it doesn't really matter if it is Stocks, Cryptos or Forex. As long as the financial assets have trends that we can identify with the technical analysis we can make a profit. The big difference in Forex and Crypto trading is in the fundamentals, which is probably why big Forex traders are not switching into the crypto world easily. When it comes to Forex trading it is very important to look at the local interest rates in a country, because you replicate any Forex trade with low risk government securities in a country. For example, if you trade US Dollars vs Euros, you already know today how the price will be in the future. Because you can sell your Dollar today and buy Euros, then invest them in government bonds with almost no risk for 1 year and get let's say 4% back. The profit you make then you can already today covert back with a contract in 1 year to USD to make a fixed profit. On the other side you have the US government bonds which for example make you 8% in one year. With that relationship you know today already that the USD in 1 year needs to rise more than the Euro because it offers higher interest rates. These relationships unfortunately don't are in the crypto world as we don't get any risk free interest with our coins. It's better to focus on one sector of the two and not at both at the same time in my opinion.
