I sent 0.55 btc to an external address with a priority charge, but more than 24 hours transaction status is just "Validating", what should I do? Whether I cancel transsaction and send in small quantities?
Is this your first transaction?
Xapo has this pain in the arse security feature where they will first asses the risk level of each transaction in order to avoid any unathorized ones. I don't know how they're doing it or on what basis but If I were a part of the the risk team, large amount withdrawals would get more attention rather than the small amounts so what you're suggesting could possibly help (although I can't guarantee it) However, it would also be weird if there are a lot of small withdrawals in a short period of time, better not do it in one go.
It is frequently another verification if ever an account gets flagged.
