I think you can do it for free. Try to learn the charts, crypto trading, Tech analysis, fundamental analysis and sentiment analysis. You can start by learning first how volatile crypto then learn all the trading signals so you can read and understand chart and learn how crypto move and what makes it go up and down. For beginner, it's ideal to start small while you're learning then invest little by little as you learn.
And it can be helpful for beginners to combine manual trading with the trading bots. You can setup them and get some profit. Last time I use tradesanta.com,  I think it works well.
