Hello everybody. Today I replaced crankset completely (the one that is inside with bearings). My Crankset little bit lose. Its invisible when riding, but when you shake one pedal, the displacement is about of the size of this dot > .

You need to identify if the crank arm is loose or the bottom bracket is loose. When the crank arm moves that little bit, does the crank arm on the other side move with it? If so, it is a BB issue. If not, then you need to tighten the crank arm screw/bolt behind the cap. Get it very tight. Riding with the crank fixing bolt/nut loose can ruin your crank arm.
