Bitcoin help

Well, I have like 30 euro worth of btc on blockchain, but when I go to send it says there is none available at this address. I checked and my address is different from my first one.. How can I change it back?

This might be a stupid question but I'm not very experienced with BTC.

You always get a new address so you don't need the old one. That makes it harder to track your bitcoins

If you are using blockchain, you should always use the new address.

Every time you're using different address.

Blockchain uses multiple addresses so you can't be tracked. What's most likely has happened is you've accumulated a lot of very minor transactions(.5$), and blockchain displays the balance of all your addresses.

Ehm, then try the other address? I dont understand what the prob is lmao

Somewhere in settings it lets you view all your addresses you used. Regardless, you don't have to change it back. You can keep using old addresses even if blockchain changes then
