yeah, dont know what happened to my first address, sorry about that
Yikes, you lost 0.01790317tBTC? That's over half of a whole block subsidy on testnet.
yup, dont know why my address changed :,)
Just wondering, which wallet software do you use? Some wallet may show different address after previous address receive coin to improve user privacy, but you should able to spend coin from any generated address.
i use electrum, i restarted my pc and i had none of my addresses, no backup, no nothing
