I couldn't agree more to this statement "The more people use it, the more powerful it would be", bitcoin has power because bitcoin is mostly used. For example, when I still didn't have any idea about cryptocurrency the first thing that was introduced to me was bitcoin. That's how powerful bitcoin is, it is now becoming a layman term.
It's also possible that the bitcoin world gets crowded that chaos started to happen. Right now, the only ones in the bitcoin world are those that are tech savvy and are intelligent enough to understand all this. Soon enough, the uneducated ones will come in and there will be chaos like what's happening on everywhere they go. Some people only seek to destroy everything that they come across. If bitcoin becomes so popular, even this people will be here. Destroying and spamming stuffs around.
You were introduced to cryptocurrency and then quickly introduced to bitcoin. Why? It's because bitcoin is the leading crypto-coin. Its "power" (as you mean it) is only limited to the cryptocurrency world. Outside of it, on the other parts of economy? Bitcoin is nothing. Fiat is still leading.
