Hey I tried buying some QUA via Myetherwallet... I did everything as stated. I set gas limit to 200000 I sent my coins to the correct address. Nothing could have gone wrong but twice now I got an error that said bad instruction... I don't know what to do with this...
I may be wrong, but you can buy quantum on exchanges like gatehub or livecoin, not through Myetherwallet. With Myetherwallet you just send eth to you address on the exchange and then buy quantum there.
