i found a crack underneath the handlebar, is it okay to keep using it? because i can't really afford a new one. I'm riding with the cracked bar right now and there's no weird sound and movement on the handlebar.

It's unclear where this crack is. And be sure you know the difference between a crack and a simple seam left in the piece from manufacturing.

The underside of the handlebar or stem is a strange place for a crack to develop, the material there is under compression rather than tension. If there is a dent there may have been an impact. Is this on an MTB? Did you crash? Adding a well lit photo to you question will really help us help you.

DONâÂÂT
If you are sure (or have strong suspicions) itâÂÂs a crack and not just a scratch, stop riding it.
From your description IâÂÂm not sure whatâÂÂs actually cracked (stem, forkâÂÂs steerer tube, frameâÂÂs head tube?) but replacing it is much cheaper and less painful than new teeth or sitting in a wheelchair the rest of your life.
Post a picture if you want a more accurate assessment but generally the only components on a bicycle where IâÂÂd be okay with imminent failure is anything related to gear shifting or attachments such as bottle cages or mud guards.
I'm sure its a crack it is on where i install my shifter & brakes i can feel a dent on it too. Okay, ill stop riding riding it for now.

Ah, so itâÂÂs the handlebar? You can get a new one for 10 or 20â¬. Stems are also quite cheap. Only frames and forks are more expensive.

If the crack is in the handle bar, the failure mode is as follows:
One side of the handle bar breaks off.
You fall forward, one hand pushing the broken off handle, the other hand pushing the still connected handle.
This falling motion will steer your bike sharply to the side with the broken off handle, effectively kicking your bike out from underneath your butt.
You will make contact with the road at your full speed you where riding at.
The resulting damages depend on your exact speed and road conditions, but I've had this type of accident once at about 20 km/h on a smooth surface (no sharp edges or bumbs from tree roots, uneven sidewalk tiles, and the like), and it's still the third most severe accident I've ever had.
Note that the energy that goes into bruising you will go up with the square of your speed. So, with 30 km/h you have to expect more than twice the injuries than with 20 km/h. Do this with 40 km/h, and you'll have to hope that your are found before you bleed to death.
A crack in the stem itself may give a similar failure mode, or it may break directly forward. I don't know what would happen in this case, but my intuition tells me that this would be much more dangerous than falling sideways at full speed.
Bottom line: Your fork, your stem, your handlebar, and your steering tube are too critical parts for your security to ignore cracks. If either of these fail, there is no backup, and the failure modes are scary. You won't have any chance of mitigating the consequences of the crash.
