Now I can see the transaction after 10 hours in blockchain. It is still unconfirmed but I believe it'll be confirmed eventually. Trxid is 388dcd050448f4462f1b453699106c3f880ea59273462a4cfdbd6554a76ef2e6 I guess there is nothing to do other than waiting. Is there?
Unfortunately it spends unconfirmed coins sent to it from earlier unconfirmed transactions. There's three chains of unconfirmed transactions that all sent unconfirmed coins to the address used in your transaction.
This is the first transaction chain that sent unconfirmed coins from one treansaction to the next in a series of five transactions.
You can do nothing and hope they confirm, pay a miner to confirm them, or try using the free viabtc accelerator (although it would probably take over a day to submit that many transactions to it).
