Altcoin nowadays are listed on some exchange which has high fees. I tried to trade to increase my portfolio despite of this situation but still useless because of the amount of fee is when it comes withdrawal.!
Is this normal because of the current situation of market? Or a normal amount of fee especially if the exchange is not yet popular?
Usually, fee depends on the coin you want withdraw. It is true that on many exchanges these fees are very high. I usually change altcoins to Litecoin - from my observations LTC has the smallest fee. Try in that way

That's right, changing coins to other types of coins will reduce shipping costs. However, if the exchange does not provide certain types of coins or a very large price difference then it will also result in other losses. So basically we must really think carefully if we will do that.
