I do mining on the pool
https://www.[Suspicious link removed]/site/mining and get a lot of blocks, but why my balance is not visible? and there shows payment
That mining pool is doing something completely different .. any terracoins mined there would not be able to be used on any exchange as they are basically a different coin. Looks like they are running old code before auxpow was even implemented... so code from a couple years ago at least.
I would pick a different pool that can stay up to date with various coins code.
