I have some BTC in BitGo because it has instant and free deposits to Kraken. Today I was trying to deposit to the exchange and naturally, since the transactions are supposed to be instant with multisig I chose the slowest confirmation option. This used to be instant, but today my transactions are yet to confirm.
Hmm, it should be instant! kraken haven't yet stopped using bitgo service, in the email they said, one can deposit to bitgo address till 30th october. did you generate a new bitcoin address and did a deposit? they might be using normal bitcoin address, if you generated a new one.
