There are altcoins that I buy for trading and I always set my sell order to only x5 of principal value. But there are also some coins that I hold for long term like bitcoin and xem. I do not sell these coins even if the price is fluctuating really high.
Not all people have this commodity to buy and hold them for many years, personally it depends from the time and situation but my minimum sell order is +0.8% of what I bought (it may sound really low but it's better than losing a lot).
But in other cases I prefer to make sell orders +3% - 5% depending on the exchange rate of that coin but also the amount invested and the situation if it is at the pump or dump phase that coin.
Thank you...
I don't think that it sounds extremely low if the funds are there to make up for the difference of the smaller profit margin.
I've noticed that most that have lower funds will hold for higher %s, but others who have large funds can take a smaller % and still pull the same overall.
I've think I have my game plan currently, we'll see how it pans out.
