Do I need to be an active day trader in Robinhood to use BlueChip?

No. Since Bitcoin isn't regulated, you can trade it freely without meeting SEC's requirements of a pattern day trader.

Day traders in Robinhood would normally have to disable their instant settlement in order to day trade securities. Cryptocurrencies aren't under the same restrictions as other securities for day trading. That means you can leave your account as is and you won't get flagged for day trading as BlueChip runs.
