In order to ensure the security of cryptocurrencies, I recommend against going to small exchanges to trade your altcoins. If there is no transaction volume, your transaction will be difficult to succeed, and the withdrawal fee will be wasted.
Instead of looking out for small exchange better concentrate on the higher volume exchange where withdrawals are very transparent because firstly we should safeguard our funds because of a small exchange there is no guarantee whether our withdrawals will be safe or not.
