It's impossible always to sell at the top. If you got some profit be happy. I hope the other coin you bought will bring you luck.It's market's nature to go up and down.
hoping for a price that is always above and good can be but not least do not bring good luck because now many altcoin are hard sold and there is no price even though we have got it.
almost all Altcoins are down, current market conditions are still unstable, often going up and down. Everyone hopes that in the future it will be fine, Altcoin that many people have the hope of Altcoin will bring good luck. when conditions like this to avoid loss you must still hold your coin and when the price has stabilized and rises high you can release it and get profit.
