I took the coins as soon as they appeared on the exchange market. For quite a long time the price goes to the same place. It would be good for developers to bring the coins to exchange large and then increase speed and increase the price.
Large exchange really needed for Mart, and i hope is the choice from all the developer team
There will be more ways to buy/sell Mart once mainnet and the actual token is released. Some of the larger exchanges are likely hesitant to add the temporary waves token.
