Kraken exchange seems like one of the more complete, legitimate, and comprehensive exchanges out there. Support seems to be overwhelmed right now. Post your problems and solutions here.
let's start with - legitimate = conforming to the law -
Kraken is out of law because it's not a licensed money transmitter business(MSB) in any state so they are operating illegally (in USA for sure)
What does mean? Well, we know what happened with other unlicensed exchangers in the past . Overnight, FBI closed their websites and they arrested the owners. Client's funds? Gone !
So, you decide if you assume this risk along with others that derives from BTC market.
