Don't ever use kraken to buy/sell your cryptocurrencies.

Without warning in advance they have stolen the bitcoin golds of their customers.

Bitcoin gold is a recent hard fork (a bitcoin duplicate). kraken is in control of their customer private keys (so they control their bitcoins) and, in an absolute abuse and theft, they are not giving their customer the newly created bitcoin gold. They are keeping for themselves millions of dollars of customers' money.

You have been advised. Don't trust in thieves your hard earned money.
