As of my last knowledge update, Studica.com primarily accepts traditional payment methods such as credit cards and PayPal. Cryptocurrency payments are not commonly listed among the available options. However, payment methods can change over time, and Studica may have introduced new payment options since then. It is always a good idea to check the current web page for the most up-to-date information regarding payment methods. If you are interested in using cryptocurrency for your purchase, reviewing the site may provide clarity on available options at this time. It is also beneficial to stay informed about any potential updates regarding payment methods that could accommodate cryptocurrency in the future.
