Altcoins I know :
Monero - I will invest as it is profitable for me
Dash - I may invest
Zcash - Not for now
Dogecoin - Very less returns
Litecoin - More like dead coin to me
Byteball - Will not invest
Eth - Will invest soon
Ripple - No as it is good for businesses and not for investors.
Somehow I don't interested on : whether monero or even ethereum to invest, only byteball which attracts me. Not only market cap, but people interest to this coin.
