1. transaction id: b55a68e7f9a4f336469068d9dacf4457aa0f72e2db4605dd2aedf87456d50b24
2. sender/receiver: sender
3. addresses: 1NHwR3ey59QM2TZdC3MJcge4GvYu9wBWRN is my address(I am using Bither HD wallet, the address always change), 1M5GFFNdDq3HznQaDGV99Vh6GGXfopC7df is the receiver's address( this is also my address,but controlled by Bitpie wallet, because i don't have the private key)
wallet software: Bither Hot 1.7.7 on iOS
mempool: yes, i have checked http://www.mocacinno.com/page/getraw, entered my transaction id, and i was shown the raw transaction, so this transaction is in your mempool
something strange: yes, I have contacted Bither's support team, they only ask me to use Bitpie accelerating function which costs thousands of USD.
rectified situation: No, the wallet doesn't have a dynamic fees function
tip: yes, I use my Bither HD wallet( my address change to 14KRVcjFD5MD5pdw6t94VXxQ2Hfdgx46Ls recently, can't find this address on blockchain.info) to send 0.00271635BTC, but I cannot found the transaction id, please help!

Maybe Bither wallet is scam?
I still have other unconfirmed transactions id:

I have no idea what's happening and what should I do, please help!!
Thanks for your concern.

Q1: What's happening?
A1: IF you want a 95% chance of getting into the next 3 blocks, you need to pay a fee of 480 sat/byte. If your transaction is using the output of an unconfirmed parent transaction, it cannot be added to a block BEFORE the parent is added to a block either.

Let's look at your transactions
b55a68e7f9a4f336469068d9dacf4457aa0f72e2db4605dd2aedf87456d50b24 => fee of 10 sat/byte, and using an unconfirmed parent!
20f341efceae193b7eb79e6c990735a4b7659d41536c1dc187324ccf40a53ea4 => fee of 44 sat/byte
d8b5b81a6295c4ba2291549096bbd0b0c7aafa2cca833e6506f701fdf39160ca => fee of 57 sat/byte
b55a68e7f9a4f336469068d9dacf4457aa0f72e2db4605dd2aedf87456d50b24 => fee of 10 sat/byte, and using an unconfirmed parent!
c7b475c3e3284af39aebe3172a3d1d21daada8aa708c6d802310a165ab8b39d4 => fee of 677 sat/byte, but using an unconfirmed parent with a fee of 10 sat/byte!

In short, a miner choses the transactions with the highest fee/byte of transaction data to fill the blocks he's working on. The transactions you created are not appealing to him/her, the odds of these transactions ending up in a block without any intervention are very, very slim (but they do exist tough!)

Q2: what should you do?
A2: first of all, switch to a decent wallet... I have never used bither HD wallet, nor bitpie... But if they didn't even warn you about the fee, nor the fact you were using unconfirmed transaction's outputs to create new transactions, they don't sound like good wallets to me.
As for your problem with the stuck transactions, there are 4 possible sollutions:
1) waiting it out.. Just make sure bither isn't rebroadcasting your transaction and wait for a couple of days (and possibly repair or rescan your wallet)
2) use the output of the unconfirmed transaction to create a new transaction with a fee that is high enough to cover both the initial transaction and the new transaction (CPFP)
3) double spend the unspent output that was used as input for the hanging transaction
4) pay a miner to include your tx in the block he/she is currently working on. viaBTC, btc.com and f2pool are known to help people out if they pay enough (do expect to pay a big premium on top of the "best" fee)

How to prevent wallet rebroadcasting?Can I do CPFP with electrum wallet? How to double spend the unspent output?or Would you please help me to confirm?
I need some instructions of manipulation. Thanks some much!
Btw, the tipping sent to you successfully by paying 0.001BTC as the fee, so maybe you can only receive 0.00171645.
