Should be illegal for this company to operate as they do.
They are getting filthy rich the way the trading platform is designed. They are nowhere up to par as other cryptocurrency trading platforms are. Also, they can control your funds and hold them for days if you want to send to other exchanges. I do most of my trading with the " Big 3" exchanges and never, ever, had issues sending to other exchanges before. I just had an experience with them recently. They tell you all these excuses that you should read the fine print more carefully and they operate as all banks do about holding funds. I found it very funny that after talking to my banker about this that he said it's one way they can draw interest off your idle funds holding it even though we immediately clear all funds when it's transferred to the exchange. I do think Coinbase has seen a influx of people buying crypto and immediately transferring to other exchanges that it pisses them off. Look, it's not like they are making any money. Your hit with the highest fees in the industry and your charged with selling, trading, buying and even sending off to other exchanges so don't tell me they are not getting a big slice of the pie. If your a small trader and fees and fractions are not a issue then Coinbase may be for you. It is also one of the simplest and easiest trading platforms. Eventually, they will have to change the way they operate when it's a regulated industry or they will be eating crow for lunch.
