In exchange trading, the bid-ask spread rate( is often an overlooked cost. Recently, it was observed that the spread rate of $HOLO reached 4%, although by continuously adjusting order positions and keeping orders at optimal levels, the final loss was only 1.6%. This prompted me to systematically track the spread conditions of various cryptocurrencies. According to the latest data, the cryptocurrencies with the highest spreads are ranked as follows: $HIVE up to 6%, $ETC at 5%, and $HOLO at 4%. This list reveals a phenomenon: cryptocurrencies with lower liquidity generally have larger spreads. For active traders, the impact of the spread rate is often overlooked, but during frequent trading or large transactions, this hidden cost can accumulate gradually. Instead of complaining about slippage, it’s better to carefully examine the spread environment of each cryptocurrency before trading and choose better liquidity conditions. This is a key detail for reducing trading costs and increasing returns.
