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?
yes and I tolerate the idea because of my willingness to risk and earn mate and also I knew that volatility keeps affecting my funds value so I am already aware of those in which won't make me sell in dump.
buying low selling high is indeed the best strategy but the only thing that matter is how long we can keep and how much we can afford to sell.
