Yes, you can buy SRK on Coinbase. However, due to its low market capitalization, SRK is not currently listed on Coinbase.
NOTE: WARNING: It is not possible to buy SRK on Coinbase. SRK is an alternative cryptocurrency, not a Coinbase listed asset. Coinbase only lists certain types of digital assets, and SRK is not one of them. Investing in cryptocurrencies is highly speculative and carries a high level of risk, so please exercise caution when considering any such investment.
You would need to first buy another cryptocurrency that is listed on Coinbase, such as Bitcoin or Ethereum, and then use that cryptocurrency to purchase SRK on another exchange.
