If I set a 3% loss on my initial investment as a stop loss and a 10% profit as a stop for selling, will that make me trade too often ?
I guess so but I think that you should be upping your 3% loss. It is usually normal in crypto to have that kind of loss. I guess you should try 15% loss and 20-25% profit to gain more. That's what I'm mostly doing and for me, that kind of percentages are good to me as a trader.
Depending on how much you can risk on basing with your capital but i do agree on your point that 3% is just a normal loss or gain on crypto thats why it would be good if you set higher percentage but still its up to the trader on how much he can risk on and possible profit that he do target out but since doing active trades will monitor out which you can eventually adjust once you have seen how the price is moving.
