Perhaps you forgot or didn't know. But when you say "always working" it is worth remembering that Kraken had encountered serious problems in the past when their trade engine was completely unusable, no action could be done, and at times it was even impossible to log in. Knowing that these recurring problems lasted
several months.
As for nominating Binance, I don't know if we can call it trusted when we know that there is wash trading on the platform and they hid it when they bought out Coinmarketcap and decided to rank platforms depending on web traffic and not volume

Or when the site was hacked.
I guess you are not aware that Kraken have been attack by hackers.
Where have you seen Kraken has been hacked? Source or it didn't happen.
