It is true that various credit cards bring with them all kinds of benefits. However, it is highly recommended that you do not buy many credit cards. Firstly, keeping multiple credit cards unnecessarily burdens you financially with paying an annual fee for all these credit cards. Secondly, multiple credit cards result in you submitting personal information to different banks and credit companies, this can increase the chances of financial fraud. Thirdly, you would have to pay interest on credit on every credit card you keep.
