Like others here have said in USA all trades on crypto is taxed as property, whether you cash out or not... to pay the least amount of taxes you need to go 12 months without trading an asset so it becomes a long-term capital gains tax over a short-term and its considerably less % wise, but your potential earnings not daytrading could be less, so you'll have to weigh these two options... and if you're in the USA and are attempting to avoid paying taxes, then you shouldn't be day trading on coinbase/GDAX because they will 1099K you if you clear a certain threshold of trades... the system is borderline criminal when it comes to how its taxed and its fairness, but the flipside is if you owe a lot of taxes, you made a lot of money and that I guess makes up for it. Places like Binance currently do not report taxes to USA so its probably okay for now, but you have to report you have money overseas or you can be fined.. and you never know what 5 years from now may look like, and you may get back reported. You'll have to analyze your risk/reward ratio of all options yourself.
