Why is a credit card needed?

Hello folks, Due to some financial crunch, I'm planning to get a credit card but I've heard from people about the scary stories of credit cards. Can any body who owns credit card can give his experience or any tips what card or how to use the card or any other general advice. I just want to use cc for online purchases and maybe in emergency situations. Thank you in advance.

I will complete 3 years as a professional soon. Quit a Big4 to join a startup for better pay and faster growth but despite putting in my best work and leading initiatives, going above and beyond all the time, my peers are all earning better than me doing similar jobs. i never had a financially aware upbringing. my father put us through hell due to his bad decision making and despite me being very financially savvy, am unable to save any money because im so anxious I tend to spend what I dont have. i had to take up a lot of freelancing to aid my lifestyle but now im busy all the time and have no time to myself. idk what to do. idk how much savings my parents have since I live away from them and dad never discusses his larger financial plans with me. he also does not have a stable job even at his age even though I know he is v hardworking and does his best. i feel i will never have enough money to support my parents and myself and feel like im running out of time. also doing interviews to leave this shitty company as well which is lowballing tf out of me. im not sitting idle at all, trying to startup on the side as well. i workout, eat and sleep healthy, have a great social life. the only problem is money which im constantly worrying about. i feel its a generational curse passed down to me. I know I have 10x earning capabilities but its all so vague and uncertain. I have an amazing support system and I know I can talk to my friends about this too. just thought of coming here first please share stories if youve ever felt this way. open to advice feedback ideas. how did you get out of it? what can I do? what are some business/sales roles that pay really well that I can get into as an ex-big4 analyst? i dont think my current profile translates well anywhere. f*ck this company honestly. probably the worst decision I made coming here :(

I'm 24 and haven't started using a credit card yet. I don't even have one. Am I going right or wrong??

How to increase my credit score , it had fallen due to Over utilisation of Card ♦️♠️

In this month alone i got 3 new credit cards. Yes bank approached me saying there’s a pre-approved credit card, which will be the fourth one. This will be the fourth enquiry on my CIBIL this month, but none of them got rejected. Current score is 770+ and age of credit is almost 3y My understanding is having more credit limit will help keep Credit Card Usage index below 20-30%. Is this correct?

I have 5
