Hello everyone, I have a question if someone is kind enough to explain it to me.

In the image, it shows what I have in my account and the two currencies I have at the moment. The $BMT was given to me as a reward in #aprendeygana .

That currency appears to be blocked for 150 days, the account was at 0.81 and dropped to 0.79.

My question is:

Why is it blocked and why is the account decreasing? And what should I do with that currency?
