Same fucking question all the time , dude you're asking a question and after that you're making suggestion of good altcoins to buy? What the fuck is this man ? Anyway do your God damn research and stop being lazy , there are more than thousand of altcoins there in the market and every coin could be the best investment for some time and then it could be dumped so try to find the best by your self because in the end you can blame only yourself if something goes wrong not the person who suggest you the investment .
