I think that there are many ways on how to earn money using crypto but I am not sure that I know all of them. To my mind, it is better to hold crypto like btc for some time and then trade it when price is high
I agree with you mate , there are lot of ways how to earn in crypto but just like I am not familliar of some. I only know is to join signature campaign or invest in bitcoin and hold it and wait for the right time to sell.
