I mined coins yesterday all day and got a few thousand. Today there is nothing in the wallet. Do not waste your time on this.
This is a test net, man! Find bugs, report them and they will fix them. Help or move on. I'm not the one to tell you what to do, you can invest your time and money in this or not, but unconstructive and hateful remarks don't help anyone. Hmm, unless if that's your purpose or you are from competition

A couple hours ago, we released an update 3.5 and a hard fork resetting all the wallets to 0 WebDollar is in test net, so everything you mine are Test Net Coins and many times when we do substantial updates, we create a new hard fork for the miners resetting all the wallets in the system. Before the launch of the Main Net, there will be a few more updates and a few more Hard Resets.
I think that you need to warn people about this in advance. Write in large letters in the first post of the topic. For example, in SEMUX there was also a testet, but the coins were transferred to the main network. In general, I like the idea of a webdollar and I will follow it.
