There are a number of exchanges and websites where you can buy bitcoins with credit card but buying bitcoins with credit cards might be fatal to start trading. Credit cards charge you a percentage of fees for making any purchases and few peoples might find if beneficial because you can make higher profits by trading with bitcoins and can easy pay off those interest charged by the credit card companies but this is what might make you land into loss.
You really need to be a experienced trader in order to make fixed profits and buying bitcoins with a credit card is actually a risk for all the peoples who newly start trading because price change might also land you in loss and you might not even be able to pay the interest along with the principle which you borrowed from the credit card facility.
Indeed , I think I saw that in kucoin or binance? I dont remember but I saw it, and I did not recommend it. We all know that having credit will make us miserable due to interest that we need to pag aside from the money that we lend. Instead of using credit card why not having a savings so that you may buy altcoins or bitcoin from that.
Sometimes if you have to pay only the interest for using credit card to make a purchase of bitcoins can be profitable if there are no hidden charges as credit cards will charge you a fixed amount of interest which you can easily cover by trading with those bitcoins in a certain amount of time.
You have to be a pro-trader actually to cover up that amount of interest and start having you own profits on it. Credit card purchases can be beneficial as they might charge you on a yearly basis and might be their interest rate varies from 10% to 30% which is not that excess and we could manage to earn that amount of interest in 2 to 3 months of time so we can easily pay off that debts and for the rest of the months we could have profits for ourselves.
