I don't thank any coins are added to exchanges right after the start. Which means there is no set price. Which means you can request any price you want. DOGE was .0000005. then it went to 0.000002, now it's around  at the same place as it started on an exchange. But you could buy it cheaper. First people were mining millions of DOGE and surely some of them sold them quite cheap. I think it's always a good idea to buy into new coins.
