My address has changed
OK, your problem is that your address has changed.
"My address" implies that you probably only have one address, otherwise you would probably have written "one of my addresses".
It also implies that the address is associated with a person who does not have a wallet or a private key, etc. I guess it's probably a simple way to use words, but that the sentences may be the result of a misunderstanding. I can not say how much experience you have. Do not be offended, I'm trying to help, but I might be throwing my help at the wrong level. You are new here, I can not say how much idea you have.
"Modified" means to me that an old address has disappeared and a different address has appeared in its place. It seems to me that this is a possible misunderstanding of the way in which wallet addresses are used.
What the title of your question on the surface means is that your wallet looked like this
, -----------. | Address | BTC | | ------- | --- | | 123 ... | 500 | | | | | | | `----------- & # 39;
, -----------. | Address | BTC | | ------- | --- | | 987 ... | 0 | | | | | | | `----------- & # 39;
and you are surprised why your address changed from 123 … to 987 …
The addresses in the portfolios do not really change, you can generate new addresses but the previous address still exists. Usually, it generates a new receiving address for each payment you wish to receive.
Your wallet probably has a way to organize these addresses so you can see the total amount not spent associated with a single address or a group of addresses.
When I look for the information in Blockchain it is confirmed 0.00
Then it is probably true.
Sometimes transactions take a long time (potentially a very long, or forever) if the rate is too low.
I did not receive payment
The sender could have made an error in entering the recipient's address.
I have 13 addresses in my wallet but no bitcoins.
That could be normal if you received BTC in 13 transactions and then spent them all.
Remember, the clearer the question, the better the answers will be. If this answer is useless to you, try to edit your original question and explain it as if you were explaining it to your grandmother, take some time to plan how you could organize the question to make it clear to her. Do not forget to sketch the background to build an understanding of the situation. Do not omit details that may be crucial to an answer.
Only my BTC value 0.00.
