The fact that they don't update the users (like Coinbase does) tells me they don't know how to fix it and/or don't have a date they can confidently say it will be fixed. I hope it is the latter, but have no confidence. I DO worry about my money/coins on Kraken - if they can't fix their issues, what stops them from closing up shop and taking everything with them?
Kraken is a very serious exchange and one of the biggest in the whole world. I dont think they can just close their business and be gone from one day to another. Of course its always a risk involved when giving someone else control over your money, but for me Kraken is one that I trust more than many others. So far service was very professional for me. I know that there are issues with their site, but this can be fixed, it might only be because of the high amount of users joining their exchange each day.
Then why don't they update us? Why don't they address the fact that they missed their original deadline and update us on the new one? They are acting like children - not financial gurus someone should trust with their money. Because in the end, you are trusting the PEOPLE behind the site, not the site itself. If the people are not honorable, the site eventually won't be - I just hope I can get my money out beforehand.
