Answer: It's true that the liquidity of ETH, Matic, and BTC can be thinned out due to the multiple versions of each cryptocurrency. This can make it more difficult to trade these coins and can lead to higher spreads between buy and sell orders. To help increase liquidity, traders should look for exchanges with the highest trading volume for the coins they are interested in. Additionally, traders can consider using limit orders to help ensure they are getting the best price for their trades.
