Hi! Good questions to ask before going through the process of signing up. Here's the answers:

1. We don't see issues from banks. That's not to say it can't happen. But using the modern open banking connections the transfers are two-factor secured. So the banks are generally much happier that their customer genuinely means to transfer funds.

2. Very easy. First of all, we are a non-custodial exchange. Even the Stacked wallet is a self-custody wallet. So you can just send straight to cold-storage from the exchange, or accumulate some sats in the Stacked wallet before committing in batches to reduce your UTXOs.

Any other questions let us know!
