I got this Update from telegram :
On June 15, you’ll be able to transfer your Minexcoins to your wallet or list them on the exchange."
After the end of ICO, 150 000 Minexcoins will be distributed proportionally to investors, including the early investor bonuses, based on the total funds collected.On June 15, you’ll be able to transfer your Minexcoins to your wallet or list them on the exchange
But what exchange?
If you read the front page on their site it clearly says their own exchange which will host the coins to be available to exchange for other cryptocurrency will be available next year in 2018!
We planing to place on Bittrex
maybe you can also place for example on Kraken or somewhere where accept USD/EUR?
