I am a newbie in Bitcoin. I opened an account with Kraken and made successful withdrawals (totaling $350, about $200 of which is BTC). However, last night, I made another withdrawal (nearly $25,000) in BTC to the same wallet. This time, they have been holding it up until now (more than 12 hours). In your experience, is this holdup their standard practice to check for money laundering or fraud? TIA.
It's on hold, probably for security reasons, but I think they will release your withdrawal soon or you could try to talk to customer support for proper guidance.
You can also check this page and see if any of the actions you might have done could have triggered the hold on your account -
