Can the wallet that I sent it to still spend the money? Your client will have this marked as spent and will prevent you from sending any unspent coins included in the transaction while continuing to try to broadcast the original transaction. There is an easy solution, though. You simply need to dumpprivkey and add it to another client, where you can send the coins from this address to another, effectively creating a double-spend permanently nullifying the original transaction.

Most clients will remove it from their pool of unconfirmed transactions at some point. When most clients have removed it, you can go ahead and send the transaction again, this time with a higher fee.

There's not a precise time when the transaction will disappear from the network, it could be days or up to a week. This is why it's always recommended to set a transaction fee. The wallet that you sent it to cannot spend it because it's not confirmed. So you have to wait until it disappears from the network and send an entirely new transaction. Whether a sender and recipient can rely on a transaction is a probabilistic matter, but a transaction's state is binary in regard to the current chain tip.

Either, the transaction is confirmed and the money has changed hands, or it's unconfirmed and the money still belongs to the sender's wallet. Thus, if a transaction is never confirmed, the money is still the sender's. Since this question was asked, the block space demand has increased , and most wallets have improved their tooling to deal with stuck transactions. For example Bitcoin Core added the rpc call -abandontransaction and the startup option -zapwallettxes. Bitcoin Core 0.

​What causes Bitcoin transaction delays?

New blocks are mined by miners about every ten minutes. Due to the underlying technology, that process can't be sped up, and each block can also only hold a certain number of transaction data, so when there's a lot of activity happening, it creates a backlog of transactions that need to be added to blocks and confirmed. Unfortunately, if you find yourself buying cryptocurrency during a long wait period, you'll just have to be patient. You won't be able to spend the coins until they appear in your wallet. And since block sizes are fixed and blocks have to be mined, there's nothing Coinmama can do to speed up the process.

Fortunately, confirmation times are usually short - about 15 minutes for Bitcoin and 15 seconds for Ethereum. Once you see the pending transaction on the Blockchain, it's just a matter of waiting. The coins are there and there's no reason to worry that they won't go into your wallet.
