How to buy USDB in India?

Could you please elaborate on the steps involved in purchasing USDB in India? As a cryptocurrency enthusiast, I'm interested in diversifying my portfolio and USDB seems to be a promising option. However, I'm not entirely sure where to start. Could you guide me through the process, from setting up an account with a trusted exchange to actually purchasing USDB tokens? It would be greatly appreciated if you could also mention any regulatory considerations or tax implications I should be aware of while making this investment. Thank you for your assistance.
