Hi, I got my ASIC 2 weeks ago and before it was doing 100-110 USD per day, now 50$. My question is why it fell down like this? because of the Bitcoin price? difficulty? also should I sell it back else I'm gonna lose a lot of money.

The A9 would have cost you about $5000 or more depending on when you bought and paid for it. This is a lot of money, so knowing what you are getting into before hand is, in my opinion, very important.

There are lots of reasons why you are now getting less, including:

- one of the ASIC boards could have failed - so you could be mining at 2/3rd or 1/3rd of the machine's capacity.
- you are mining a coin which all of a sudden has got a big increase in difficulty
- you are mining in a pool which has had bad luck in finding blocks.
- you are mining a coin that has dropped in price a lot recently.
- you have had connectivity problems to the pool which stops you asking or submitting shares consistently.
- whether you are selling your mined coin immediately for Bitcoin

I would strongly suggest reading these forums about difficulty, hash rates, shares etc - and learn as much as you can so that you can work out the answers why as no-one can give you an exact answer based on your circumstances as only you have access to your miner.
