It's hard for me to understand that someone keeps as much as $600 000 in a hot wallet, and one simple hardware wallet costs about $50...
But keeping so much money in hot wallet, it's just so stupid and not responsible. I don't know how I can trust service which don't take even minimal precautions to protect funds of customers.
I agree with both of you but perhaps, they had to keep a certain amount in their hot wallets so they could process fast/priority withdrawals
[not taking sides].
- Unfortunately, they paid the price for offering such withdrawals [even though I'm sure they've gained a lot from those fees] and it'd be interesting to see if they'll be offering it again.
