There was more interest in inexpensive Chinese carbon frames during COVID when demand and prices for bikes were so high. Since the bike market crashed, and there are many more discounted new and used options, the cost / benefit ratio of these types of frames have dwindled or disappeared. If you realistically budget solid, proven parts, the savings over a currently discounted or used established brand are often modest at best.
Many people have unrealistic expectations about inexpensive Chinese carbon full suspension "all mountain" bike frames. For sure, they can be an adventure to assemble and fun to ride, but frustrating problems and surprises are probably more common than people expect. Fork crowns that hit the frame, suspension that gets stuck in the compressed position, or even rear triangles that can't be ridden as designed are examples. Consider what that says about the design and testing culture these frames come from. Unsurprisingly, kinematics and details like weather sealing are often inferior to name brands even when the frame is a "copy" of a well-known branded frame.
In my opinion, open mold, inexpensive Chinese frames are great for people who like a challenge and like solving problems. I don't think a 10kg 150/150mm all mountain bike is realistic.
