For me personally bitcoin is actually the best investment at the moment, even with small amounts I can earn a reasonable profit in the future for sure. But there's also some downsides - you got to wait.
Saving it can be very unpredictable, it's not very profitable if you lose everything in an instant after a few years if the bitcoin value basically disappears, which is unfortunate to say the least.
i must agree with you, bitcoin as an investment is a perfect option to choose because it will grow, its definitely better to invest money into it and not hold your fiat
