OK man, but I'm not responsible!
Like others said: Go to Coinmarketcap and search for Starbase.
Or just Google "Starbase Token".
--> First result on Google Search Results is probably Coinmarketcap.com,
second result is the Starbase website Starbase dot co (not dot com, dot co).
On the Starbase website, you'll see, in the top navigation, a pink button that says "SWAP".
This will lead you to a page on Uniswap. There you can buy.
Success!
Again, this is not financial advice. On the contrary!
If you're not capable of finding this information on your own, then you probably shouldn't buy shitcoins.
But I do want to help a bit to speed up the learning process.
