With bitcoin you never know. The rise has been steady so far, so the possibilities of another major correction are dim. With that being said, there can always be other external news (like a country banning bitcoin or crypto all together), that could make it dip or even crash. I would probably go for an investment below 0.1, but that is due to my budget restrictions.
For my opinion its better to invest now than too late,atleast if you invest earlier then there is possible that you could get good currency or good profit
