1. They reserve the right to reject, refund, or limit transactions "at our sole and absolute discretion."

2. They can impose and change limits without telling you.

3. When you "add" money to your Wise account, you’re technically sending money to Wise, and they then decide when to credit your Wise balance.

4. Even though you are the legal owner of the funds, Wise retains practical control over withdrawals, with several escape hatches allowing them to delay, limit, or reject transfers practically forever.

5. They are not reliable for anything, any errors, attacks or bugs, "unforeseeable" stuff. They can even close tomorrow and just say "goodbye" to all the clients and not be liable – there is a specific clause in agreement for that.

If you read agreement closely — Wise (and similar fintech services) often use legal language that gives them almost total control on your money, as well as reinvesting and getting interest on it while it is blocked from withdrawal on your account for, well, reasons...

I don't understand one thing; how can a Business accept such a risk? For what reward? Is there really no better solution to accept payments online? Why people keep using this middleman stuff?
