How can I do it safely and low risk?
I don't think getting yourself into trading is a good idea. By this, I mean it isn't a simple buy high or sell low game that lets you earn a quick buck without too much risk. Personally, it is the most complicated game I've seen in my entire life because you are up against people who have extensive experience, more resources, and connections that give them an upper hand over you which in turn will probably make you lose money if you don't specifically know what you are doing. If I were you, I'd rather DCA[1] while learning crypto in general just to get comfortable in the space. But if you still want to learn to trade, then I highly suggest you read these resources[2]
