The Maintanance problem has already been solved, right? I wanna try Bittrex. Just in case, I was looking for some useful advice on crypto exchanges and then I found this article - https://medium.com/@the_max/cryptocurrency-trading-tips-6d3ed585f11e. Quite a lot of information. However, I don't agree with some points there, for instance, I don't put hope into airdrops/bounties and I don't like ICOs as well, 'cause you never know, right? So I resort to buying crypto, and one of the new platforms offering low fees and good security is GetEx (www.getex.com), if it is not against forum rules to show the link. THey are to be launched soon, so I wonder if someone has heard of them as I had?
