Trading can make you a lot of money but it's easier to make long term investments. Especially when the market is so volatile. When buying a coin I always think of the price in the long or mid term. It feels a lot safer to me. I just buy it for a price that looks like a good price for me in the long or mid term. And then sell it when I've made a nice profit and try to buy it back when it has gone down a little and then just repeat.
