It's Ok to take some profit now daily because lots of altcoins and tokens ico getting drop's its price even the project looks good but im buying only coins in a low price and start to hold it for a long term
You are contradicting your own statement. How can you make profit when the price of the coin is going down? And how does that add up to buying more coins to at the dip? Buying them is a strategic move for future and not an immediate profit.
although very little profit is not an important problem there are still advantages because many people lose their money and lose when the market is unstable like this
Those who day trade regularly put in a large volume of coins to trade. Its not like the 100$ in a month like the hobby traders. They do analysis and keep on making new orders according to the style they play with. So end of the day the "small profits" end up into large ones. It might seem as though they are losing money but they are actually fooling you.
