The last statement should be rephrased to "On the other hand, if you are a dumb you could do gambling." simply because risk takers are actually for trading and investments while dumb people who wants to feel that dopamine increase will always choose gambling even though they know for a fact that there's very limited amount of people making actual money from gambling. They do know that they can do better and attempting to earn money from gambling is a waste of time and resource.

Yes, I do agree that there is a chance of earning a lot of bitcoins from gambling but just how little that chance is? It's much better to have smaller gains but high chance of that actually happening and just repeat the process over and over again until you accumulate a good amount of bitcoins. I would always choose trading and signature campaign. Trading allows you to earn a good amount of bitcoin but it's not really guaranteed that you are going to earn. Signature campaigns, while also do not guarantee that you are going to get paid, has quite a decent pay and has a much higher chance of paying out than any other online opportunities.
