Many people in this world are always questioning this, what is a good business? Well, good business is a business that begins, rather than being questioned because the hard thing in doing business is to walk to the first ladder. If we do not start a single step, we will never get to the top. Just as with trading, or investing in cryptocurrency, without trying and starting investing in it, you will not know how much profit you get, and how much experience you will receive if the market is down. Remember that experience is the best teacher.
I certainly find this idea interesting, well, we can really come up with a good sense of idea what kind of business to start up what and what, what is what, and actually it really make you expose to the boundaries of business but when you start this one already ,you are more likely to learn since the actual process is present, but dont get me wrong I'm not saying that you have to start eventually and learning nothing.
