First of all, I thank you very much because you are the first person to complete the test. Regarding some of the questions you responded to, I need to explain that the minimum recharge value should be 0.001, which is also the smallest chip that has been stored, not what is displayed. 0.01, I plagiarized the front-end and forgot to modify it. Regarding the issue of address reuse, I was actually lazy. I directly released my test environment without modification. Almost all my tbtc comes from coinfaucet.eu, some kind of Situationally speaking, obtaining tbtc may be more difficult than real bitcoin. If I recreated a wallet and generated some new address before publishing, I wouldn't have this problem. Thank you again.
