There are similarities so also are some differences. The best way to learn crypto trading is to first read crypto trading textbooks. This will give you an in-depth understanding of some basic cryptocurrency terms, tools and other important things you will meet when you open a crypto trading account. You can check some of the threads I created on crypto ebooks. Once you know the basics, then you need to start by using a demo accounts. There are many platforms that offer a free demo account.
I do not really see the need to read books specialized in trading cryptocurrencies, trading is trading and the same concepts apply to all the markets, as an example while the volatility in this market is extreme any trading system should have taken this into account from the very beginning and if this was not the case then the trading system that such trader was using was incomplete, and they would have failed in any market anyway as eventually they would have made a trade which exposed themselves to too much risk.
Reading books is just like to gain some ideas but not literally it means that this could save us from losing due to the volatility of the market and both forex and crypto trading have. Though they it look different, however, TA's and all trading strategies are quite the same.
But I could say that crypto trading is more risky, not because of its volatility as they both have but it is due to the numbers of coins available in the market and if we are too lazy to make any searches and to do chart analysis, I can imagine already what will be the result, and that certainly disappointing.
