RE:WellHey, I have to say you are not stupid.
the stock always go up and down. so does it make you smart yesterday and stupid today?
apprently it's not.
If you think it(GRB) is a long term stock then don't make a jugement so quick. just wait for half or a year more.
but if you play GRB just for short term. then you lose ,you maybe not that smart.
so the next thing you should do is find a stable way to invest your money.
maybe real estate or long term stock or BTC(perhaps) etc.
that is just my personal opinion.
