So i was thinking to test if technical analysis and trading strategies could be profitable with crypto. I would of course test everything with "virtual funds" first then move on to the real markets.
My question is where do i find the most trustable and high quality resources to teach myself? Are there any free or payed courses online? Maybe youtube channels or blogs that specialize in crypto trading?
You are in one of the greatest places for that, bitcointalk has been as old as bitcoin and it has been providing with new information (good or bad quality) forever. I think you need to really memorize everything you read here, you can then go check reddit as well because that has a lot of promising information there as well and you can check cointelegraph for the coin of your choice or just learn whats new in the crypto world and so forth. However no matter how many places you check the biggest currently happening information will always be here, you need to check the topic of whatever you are interested and people will say whatever they think of it.
