Selling at a loss and seeking a profit of 15% is not something that is very easy for me, indeed in an emotional sense you can get compensation from losses but the market will always change beyond the original plan, all you have to do is consider it very well. and be careful, there might be nothing wrong to last longer at a price that is better than it is now, as pumping Ethereum is very easy to get so don't worry, if emotions can't be held it's not bad usually all decisions are based on preparation for strategy forward.
