Could you please elaborate on whether or not it is possible to purchase SAND tokens directly on Coinbase? I've been hearing a lot about SAND and its potential in the decentralized gaming and virtual world industry, but I'm not sure if Coinbase supports this particular cryptocurrency. As a user of Coinbase, I'm curious about the availability of SAND on their platform and if there are any specific steps I need to follow in order to acquire it. Additionally, would you mind sharing any insights or considerations I should take into account before making such a purchase? Thank you for your assistance in clarifying this matter.
