My trade is taking hundreds of blocks to go through.
And I cannot deposit tokens to the exchange. Transferring from one wallet to another (one created at EtherDelta) took less than a minute. Then I hit 'deposit', was informed about transaction and... nothing happened. And I cannot retry because there is some 'error'.
Wait a day, then the deal is canceled and you can send it again, having previously increased the price of gas in the upper right corner.
And put the amount of gas 10. I have it all turns out.
