Since 2 years, it was been mentioned about thousand times : "simply add a big capacitor nearby vcc/gnd pins of the ESP"


Exactly.
But not just any old electrolytic ...
You need one with a low ESR, such as a Tantalum Cap

In all of my ESP8266 projects, I use a DC-DC convertor in "buck" mode. That way, I get a very well regulated 3.3 Volts and I get an excellent low Z from the output power unit. The units are like $0.50 in quantity from China.

Can you share capacitance(F) and voltage values with me? or any links? i would be appreciated
