#update tick size based on what crypto-pair you are buying. All BAT pairs are 6. Check out the API link below to see what you need for your pair
#update you quote_currency_price_increment based on the BAT pair you're trading. BTC is 8, ETH is 7, USD is 5

Converts all your BAT (if you have any in your gemini account) to BTC. Replace BATBTC with BATETH to get ETH instead. For another cryptocurrency, replace BATBTC with BATUSD and then use the buy scripts to continue your DCA into those tokens with your extra USD from the BAT tokens.
