Hello

I know there are thousands of books regarding tradings, in the past when i wanted to learn stock trading I joined a bootcamp and I learnt a little bit about Technican Analysis, supports, resistances and some indicatores like EMA, SMA, and so on.

1.  Does the same TA for stocks apply for crypto trading?
2.  Can you recommend me a few best books for TA crypto trading, the bootcamp I took was 5 years ago, so I have forgotten a lot of what I learnt.
3.   Can you recommend me some websites related to crypto currency trading? I would like to follow other people signals and analyze them.
4. Is there an exchange with demo accounts to try first?


Thank you
