Be careful because most of these people will be pitching the tokens they have invested into to you, and you may buy into their dump. Take the information and do your own research. Concerning exchange, don't put all your fund in one exchange.
Not the ones people would want to buy though except that Golem project. and i only invested to it because ICONOMI invested to it and i guess their decision help its growth to thier own token as well. if i have some money to invest to a particular crypto its gonna be ICN. thats just it.
