Recently I have been trying to come up with ways of making some money on the side and thinking of giving trading a go.
I have zero experience and have just been looking on Coinbase at the best and worst performers of the day.
I am thinking of buying coins that are 15% or more down and then selling once they pump 10% and move onto the next one that is 15% down and then again sell at 10% profit and just keep repeating.
Anyone done something similar or will it just lead me to losing my money?
You think quite right. But don't use much money, use only those you can afford to lose. Even with all the market predictions the market still remains unpredictable
