Some users managed to use the formed "hole" and withdrew the funds. All operations on the exchange were stopped until the moment when the programmers fix the bug.

The tokensale of the platform of the payment channels of the Etherium Raiden, launched on October 18 and organized on the principle of the Dutch auction, ended November 1 at a rather moderate amount of 109 532 ETH (about $ 32.75 million). Of course, such an amount seems to be moderate only by the standards of 2017 - especially if we recall that in August 2014 only 31,500 BTC was collected at the Ethereum ICO itself, or about $ 18.4 million at the exchange rate for that period.
