I'm not very well versed on how the blockchain/confirmations actually work. I sent a few grand in coin from one wallet (blockchain) to another (coinbase) a few hours ago... yet I have yet to see even 1 confirmation. In fact, its been stuck on "Unconfirmed Transaction" for about 2.5 hours. What does this mean exactly? That the transaction has a lower priority then all the other trades on the blockchain and is just placed in quue? Or is something fucked up on the receiving (Coinbase) end? Any insight?
