We are investing in quantum computing stocks because the quantum computing industry is projected to grow at a compound annual growth rate (CAGR) of approximately 30-40% over the next decade and as Nvidia’s CEO said, this is only early stages, so we would like to take that risk. This rapid growth underscores the transformative potential of quantum technology and the opportunities for investors in this burgeoning field.
Be aware and do your own research
Investing in quantum computing stocks comes with big risks, most of us have seen how most of the gains disappeared in just a week . You need to be aware that the technology is still in its early stages, and commercial viability may take years to materialise and some of these companies may fall on the path.
Company that are pure-play such as IonQ and Rigetti can bring big rewards, but as they are just focusing on that technology it can bring massive losses too. In that case diversification with some other big companies named such as Nvidia, Google or Amazon helps in mitigating the risks as they get revenues from many sources.
