And to be fair, the 'hiding his power' trope only works for me if the MC isn't getting looked down on or mocked by the general public, I mean seriously, the people in these novels are fucking jerks, authors these days really love it when some mob characters mock their MC for no reason just to increase the word count, if someone doesn't have talent how on earth it's his/her fault??
'Oh, you only have trash-tier talent? HAHA, eat my fist powerless noob!' Some a**hole mob character.
''Hey look! Isn't that the trash F-tier (Insert Mc's name here)? Haha, let's mock him and beat him up for no reason!" A bunch of young masters had showed up for no reason.
'Haha! Look, it's the academy's number one trash, let's mock him and laugh at him because we are mob characters and that's our only role in this story!'
And so on and so forth.
