All I have to say in the first paragraph of my review is on the bad trading interface of spero exchange. The interface of this exchange is so unattractive, unmarketable, non-stylish, in fact no word can describe how poor the trading interface looks. Me as a trader, most times I am mostly concerned about the user interface, if poor or good to use, because the interface of any exchange is the part that motivates me stronger.
Spero exchange was established in South America, particularly in Portugal. The problem of inability of instant display of most content is applicable in this exchange. Now talking on the trading fee, for trading pairs users are charged 0.15% with a discount of 50% only for traders that has more than 100 spero coin, which is the native token of spero exchange. Limited information are known about this exchange, thus putting fear into traders mind when trading.
