The major differences between day trading Bitcoin versus Ethereum or other altcoins come in the form of different market structures. While major cryptocurrencies like Bitcoin and Ethereum sport substantial daily trading volume, small altcoins may seem appealing due to the possibility of enormous price volatility, but actually be difficult to sell in the case of a thin market. Day trading altcoins can certainly be profitable, but the relative lack of liquidity and the possibility of “pump and dump” schemes adds extra risk within an already volatile market.
