Honestly it doesn't matter that Coinbase is regulated by the SEC because everyone's main concern is the volatility of the investments (coins). All firms/companies selling investment products regardless of type will be regulated by the SEC and FINRA. FiNRA is actually very good at policing investment firms (broker dealers) and their employees (brokers) regarding customer complaints. For example, if you are considering a financial planner/wealth manager, you can go onto FINRA's website and see if that person had any historical complains/settlements with clients and the same for the investment firm they work for. Like I said before, I hope anyone investing in coins use expendable income they can take a risk on.
