コインエクスチェンジに送金したが、2日たっても送金が完了せず、問合せしたら以下の回答がきた。
みなさんもこのような経験あります??
Until we see that this transaction has been confirmed on the Bitcoin network we cannot credit your account.
This may be due to congestion on the Bitcoin network or because the transaction was sent with a miners fee that was too low.
Unfortunately, there is nothing we can do until the transaction is confirmed on the Bitcoin network as the deposit has not technically reached our Bitcoin wallet yet.
Sincerely,
