There's lots of different methods to earning money in the crypto world. Day trading is probably the most common. Pick some coins that have decent price action (fluctuations daily between 10-20% or so) and buy low sell high. It may seem more complicated than that but it really isn't. The trick is to diversify your investments. Every coin in the market will have different price action so you can invest in a different one if one isn't doing well currently. The worst thing is to get stuck in an investment before you're able to get out in profit. To minimize the damage of that, don't invest everything into one thing. Invest multiple different coins. At the same time, you can minimize your risk by buying more in as the price drops on a coin as well. As the price drops and you get more and more invested, the average price of your investment per coin lowers overall, allowing you to take profit earlier when things rise again. There's lots of different methods, but you should find one and stick to it. Leave emotions out of the decision, they will get you killed in the market.
