Where can I buy some coins with the cheapest price? Too many exchanger & trading sites out there, you don't know which is the best one.
Maybe conduct a basic review or search about what is the best coins to invest in , such as the ripple and ethereum and also the litecoin , or maybe see a person then agree on something which is the lowest price you will buy , there are some market or exchanger or trading sites out there but be wise some aren't well function , some are just eating your'e money just like my friend experience.
