Smart people often would be able to identify positions of wealth in an investment and be smart enough to make informed decisions on how to utilize discovered opportunities to benefit themselves. It doesn’t necessarily mean you would be wealthy but, could be rich at the very least.
If only the investment that has been chosen is like with Bitcoin. It's true that the key to these successes is due to our good decisions of whether holding them or not. Because everyone has a mindset to become wealthy but doing that in the process is what makes the most of them give up. It's not as easy how it goes and that's why only few people meet at the top. In observing how the rich does it is easy but copying how they did it is another thing. They won't be called smart for nothing and that's why these investment decisions are not for everyone to be done because it is accompanied with greater risks for those who aims for greater rewards and results.
