I don't know how much minexcoin you have, but i think it is better for you to move your coins on wallet and going to parking. In the waiting time until new exchange you can get new mnx from parking. It's pretty safe coins, you not need to move them feom your wallet. If you have 100mnx you can earn weekly 5mnx just for hold coin in wallet.
It would be nice to earn 5 mnx ever 100 mnx you park weekly but that high weekly rate won't last long. I think over time the average weekly rate is going to be 1 percent. That is still good if minex eventually reaches 20 usd as they say in thier memorandum.
