My apologies for my late reply.
I'm sorry but I'm new to the bitcoin world. How can I ask a miner?
I listed a few that can help you. They are either a miner themselves or can ask a miner to help you to include the transaction into their block. No guarantees, I would be prepared to pay them a small amount as an incentive if I were you.
If any miner will not take this payment will I lose the coints?
3 scenarios.
#1 Your transaction gets confirmed. Yay?
#2 Your transaction doesn't get confirmed in the near future but it will DEFINITELY get confirmed if the transactions remains valid and #3 doesn't happen. Eg. you don't make another transaction that attempts to spend the same input at that transaction.
#3 Your transaction gets dropped by the mempool and you can spend your coins again, no problem. Nodes and miners will include your new transaction into mempool.
Now, #3 can be tricky to do. I'm not exactly sure about how Multibit handles unconfirmed transactions, whether they rebroadcast it or not. Your best bet is either to ask a miner to help or wait.
