My opinion it is bad for a beginner to play blitz chess. One way to improve is to learn from your mistakes and playing blitz chess produces terrible games for a beginner.
Play slow games and then try and figure out your mistakes and have a high rated player help you find your mistakes. If you know your mistakes you can correct them and thus improve your play.
Well I've recently started playing for chess and I've honestly improved alot, Im still a reltavily low level player but I not as bad as I used to been. Though almost all the games I've been playing now have been nothing but blitz and Im quite scared if my devoplment may been hindered due to the blunders and mistakes I make due to the quickness of blitz. My question is, is it a good or bad thing for a beginner to continue playing blitz chess.
