you should wait for at least one confirmation and please double check the receiving address (i dont kow him.. maybe he is a trusted trader here)
edit: missing word
Wallet address seems fine but he sent it w/o fee or with low fee & its still not showing up in my a/c.
Just wondering can this be reversed?
Its unconfirmed, so yes it can be dropped by the network and not confirm. I wouldnt do your part unless its confirmed. That is, if you still can.
Its still unconfirmed even though its more than an hour since he sent this to me.
Can this be some kind of scam?
I dont know, the fee is very low. If you want to make sure the transaction is not forgotten by the network, open the transaction itself (not the address) on blockchain.info and append
?format=hex to the URL.
Like this (should be the one you care about, there are two for the above address though):
https://blockchain.info/tx/751da63e633df680db6a29633475d11198bd096d0a75938d74f9b2cccea1da77?format=hexIf you open the URL now you will see the raw transaction.
In this example its
010000000133583ada5091dd0814ecab26beefde14aba1b9294fb8a9e28325b7a8d8d76106010000006a473044022100f596924707db95cc6e7eb7a6b976974ad0760d1f7f47c3db42a0b0a3306a5142021f039d84c7f7a93320eff9320bc3c93f11999083a022a25731da6b32249ac4c6012102cd0f397b3ad1887a1309f5b0fe914385a23804d484e21e51d9e850f7b23de716ffffffff02b075b100000000001976a9146c8aa6918f38ec13433fb57acc57bb7a44384b1288ac9635a901000000001976a91482f74b865c1646ad742fba51c7e8911a148195f488ac00000000
you can use the raw version to rebroadcast this via different platforms.
Here is a list ->
https://en.bitcoin.it/wiki/Transaction_broadcastingIf you use bitcoin core you can also do it yourself with:
sendrawtransaction 010000000133583ada5091dd0814ecab26beefde14aba1b9294fb8a9e28325b7a8d8d76106010000006a473044022100f596924707db95cc6e7eb7a6b976974ad0760d1f7f47c3db42a0b0a3306a5142021f039d84c7f7a93320eff9320bc3c93f11999083a022a25731da6b32249ac4c6012102cd0f397b3ad1887a1309f5b0fe914385a23804d484e21e51d9e850f7b23de716ffffffff02b075b100000000001976a9146c8aa6918f38ec13433fb57acc57bb7a44384b1288ac9635a901000000001976a91482f74b865c1646ad742fba51c7e8911a148195f488ac00000000
from the build in console. It will - due to the low fee - probably return an error though.
Rebroadcasting a TX will make sure its not forgotten which makes it very difficult to double spend. It can still take a long time to get confirmed (think days or weeks with a fee that low).
