The list are consists of potential altcoins next to eth and xrp but as a trader I keeping my funds for trading good coins that has been traded across different exchange. My strategy is more on arbitrary but using exchange such as Bitmex and Binance is also good using margin and future trading.
Those coins are literally made by one person (or a team) to make themselves rich and not for everyone else use.
BCH was first created because bitcoin moved towards segwit and other stuff in order to not pay too much transaction fee and make it faster and cheaper to send and receive bitcoins, miners of the world (Jihan Wu and Roger Ver as the lead) said that it would drop their profits and they will make less money because of it so they literally decided to have a hard fork of their own version where they would make more money whereas people who send and receive money would have to pay more than they are paying on segwit.
I don't even have to explain XRP, those guys have been around for years and they have been stealing money from the public all those years, if you still believe in them, not much I can say would change your perspective.
