Unconfirmed transaction: S this is the hash:

Eff686ec0d9950eb0d1c1cef52287ad51369144e1a1de8143ff3b2370694f978

I bought them yesterday to a contact that I met online ... we made the transaction in person and ready we left .... The transaction was made yesterday at 11:23 am (Venezuelan time) and at this time 18: 04 nothing yet. I'm really worried. I have done previous transactions of up to two hours and now this. The transaction was made from Blockchain to Coinbase.

Blockchain tells me that the transaction was received today at 4 pm (I do not understand if I did yesterday)

Instead here if you tell me it was made yesterday at 11:23 am:

Please someone to help me and guide me on this thanks

The times that the block explorers report do not matter and are typically not reflective of the time that the transaction was actually made. Ignore that, all that matters here is the transaction id.

There are multiple problems with your transaction. First and foremost, your transaction spends from an unconfirmed transaction (I will call this Tx 1): https://blockchain.info/tx/0cca850d39a87be0c6e958049ede276cca19bebc8c68a809e3e3b5bd31b03a1f which spends from another unconfirmed transaction (I will call this Tx 2): https://blockchain.info/tx/3ffbe09b0967b52dbda5ef46995a420dae5c227a92bd3baecb2041842cf99b6e

Your transaction cannot confirm until Tx 1 confirms, and that cannot confirm until Tx 2 confirms. This is what is primarily preventing your transaction from confirming.

Tx 2 pays a very low transaction fee, only 35 satoshis/byte. The current recommended transaction fee is 160 satoshis/byte according to http://bitcoinfees.21.co/. Tx 1 and your transaction also pay fairly low transaction fees, only ~65 satoshis/byte.

Unfortunately all you can do is wait or ask a miner for help. For asking miners for help, you can contact the users Quickseller and macbook-air. You can also try using https://www.viabtc.com/tools/txaccelerator/ to "accelerate" your transaction.

With waiting, since you are the recipient, you want to constantly remind the Bitcoin network that those three transactions exist so that the sender does not scam you by double spending the Bitcoin so you should constantly rebroadcast the transactions (although rebroadcasting does not prevent double spending, it can make it harder to do so). To rebroadcast the transactions, get the raw transaction by appending ?format=hex to the blockchain.info URL's for each transaction. Then copy and paste everything you see in that page (should just be a blank page with a bunch of random looking letters and numbers, that's the hex code of the transaction) into https://blockchain.info/pushtx and push the transaction. Do that periodically (maybe once a day). Other people can and probably will also rebroadcast the transactions for you.

Why would he rebroadcast constantly instead of spending them with a high fee of 0.001 to make sure 1 confirmation at least in less than 10 minutes?
That should confirm the parent unconfirmed transactions as well right? it's not a small amount so paying $1 buck for making sure receiving the already bought coins is nothing compare to losing all of it.

I really am new to this btc ... I always thought that the transactions were irreversible once they were sent ... I do not know what to do really: s here in venezuela those 70 $ is a lot of money .... are weeks of work ... I did not know that I had to wait 10 minutes for the confirmation ... and I almost do not understand what I recommend the first comment: s ... god I do... very thank you so much

Tomorrow I will try to do what you recommend ... although I understand very little .... thank you very much

Because he can't. Almost no wallet allows you do make a CPFP transaction because that involves spending from an unconfirmed transaction. Given that he is using either Blockchain.info or Coinbase, he basically has no access to the private keys in order to even attempt an advanced method of making a CPFP transaction.

Secondly, I'm not sure how well a CPFP transaction would work for covering three ancestor transactions. Also, the fee for that would cost around 0.002 BTC because it has to cover 4 transactions of unconfirmed transactions.
