The transaction contains an input from a previous unconfirmed transaction (actually there's a chain of these unconfirmed transactions).
You can follow them on blockchain.info by looking at the inputs - one of them has a red "U" which means the transaction from which this input came is unconfirmed. Click on the "output" link next to it, and you will see that transaction. The original unconfirmed transaction in the chain is

That transaction did not contain a miner fee, this is probably the reason that it isn't mined yet. Once it is mined, the others in the chain will probably be mined as well, either in the same block, or in one of the next blocks.

That's seems i find finally good place to ask this question i tried LBC no luck there - they even confused me more..
ON StackXchange for Btc no answer - only someone edited my mistypo and left me -1 point lol
I tought it's something like that just i tought U means something much worse like Unaothorized or something even worse...
So i can basically stay calm about recieving this money sooner or later ( When the first Uncofirmed trans with U get mined finally)
??
Or is there still even slight chance to reserval back to sender?
Is there even way to post such transaction bitcoin so it get stuck on 0 Confrmations and finally reverse to sender ( cuz i sended the stuff i werer selling instantly when i saw btc in wallet - didn't tought it may not confirm)
Sadly there is a chance of "reversal" at least as long the transaction stays in the unconfirmed state. The longer the transaction stays unconfirmed the higher chances are that the network will forget about it. This happens quite simply because nodes restart or otherwise clear their memory. Transactions without fee are very low on the priority list for miners, thus there is lots of time for the network to forget about the TX.
But there is also something you, or anyone, can do. Remind the network about the TX. Take it in its raw form

and rebroadcast it either with your own full node (like bitcoin core) or use a service that allows this, like these:

https://en.bitcoin.it/wiki/Transaction_broadcastingYou can do this for the whole chain.
#1 take the link on blockchain.info with the TX ID and add ?format=hex at the end
#2 copy the rawtx, e.g. into a text file, in case blockchain.info forgets about it
#3 rebroadcast it 2 or more times a day, until the TX is either confirmed or invald
Invalid? Yes. When the network forgets about an unconfirmed TX the person that originally created it is free to create a new one using the same bitcoin. This is commonly known as "double spend" even though its technically not one, because the TX was never confirmed, but its as close as you can get with bitcoin.
This newly create transaction can be created paying a fee and has a higher chance to get confirmed. If you keep broadcasting the chances are very small that it will work, because a node will only ever accept one of these TX. As long as you make sure the network knows about the old one, its almost impossible to replace it with another one. Some wallets may even show these two transactions as "conflicted". As soon as one of them confirms, the conflict is resolved. The confirmed one is valid, the other invalid.
This might have been a bit much, feel free to ask questions.
