Inputing private key is a annoying for me since I am doubting to put it again on fork delta since they have the same interface with ether delta which is shady exchange to. And I would rather trade on the other trusted exchange around than to trust this trap exchange.
Use MetaMask bro it is a handy app, I won't ever use my private key to access both Fork and Ether deltas.
I buy tokens on ED but you should pay attention at ETH network difficulty because some orders could not be updated!
Once I thought I could make a deal but the order has been already completed but remained to hang in the orders list.
