Almost all exchanges have fees and minimum limits in withdrawals for their users, and of course as users we must be observant in choosing altcoin which is good for to withdraw from the exchange and one of them is by choosing altcoin which indeed only deducts a small fee as transaction costs, my advice is better to choose altcoin withdrawal from the exchange by using altcoin which does have a cheap price on the exchange because usually the altcoin fee will not be too expensive, I often make withdrawals using ltc, trx, and eth coins in certain exchanges.
