Actually, those coins will depend on the USD rate and the BTC of it so still depends on you how you manage to deal with the market volatility of those pairs, in just my cents if you can make a ride with the market price movement deal with it no too much advice if you can do it at your own. People always grab the buy and sell pressure small profit still consider a profit so its up to you if you want a big percentage just to share to your profile or just enough to call a day as a profit.
