Hi, I have a problem to withdraw Bitcoin from Bitfinex.
When I try to withdraw I am asked for an SMS to be sent to get a Code. When I confirm sending an SMS an error occurs that SMS could not be sent to that number. When I try to change Settings of SMS and 2-Factor-Authentication  I need an SMS-Code to confirm that action, which I
don´t get. Has anybody had this problem before or does someone know a solution for this?
Thank You.

Hi, I have a problem with an ETH transaction. About three hours ago I´ve sent 0.12305702 ETH to this address: 0x90863225823894c52faf62043a694ff4f3f00520
I used the address before without any problems but now the transaction is still pending, I don´t see any confirmations on my coinbase account and I don´t even see the transaction on etherscan.
Can someone please help me with that.
Thank You.

Hi,

I have a problem with a BTC transaction that I dont understand. The transaction is stuck and my wallet says "replacable"

I sent 0.015 BTC to this address:  19ppUZex1DUNTUzDxyhNe7B4LDLcrTHVEJ
The fee of 0.00062719 was also paid.

When I look at the transaction on blockchain.info
7443d1e5f00fa0b57a60870805e71b18e4b14d7949c50b8c8f4d64880bda0e3c

there is another 0.000051 BTC sent which is not from me. Is that the problem?

I dont understand that, Please help.

Thank you for the answer.
Does that mean that the transaction will be executed later or do I have to raise the fee? I could do that. The Elektrum wallet allows to that.
What is the best thing to do? But not do the same transaction again, right?

Hi,
I have a problem with a transaction.
I´ve lowered the transaction fee manually to 120/KB and after I had done the transaction there is a triangle with an exclamation mark in the list of transactions. 
Behind it there is the word "replacable". What does that mean?
When I click the transaction I can read the transaction time is 25 blocks. What can I do?
Thank You.
