bitcoin is in the dangerous place. it's touched 21.5k resistance before so if its break 21.5k it will go to 18k again and be there for while if 21.5k resistance don't break it can back to 24k and yes its for short period. for long period (weekly) it will back to 40k (the real price of bitcoin) i put my half money on 18k and other half on 16k
