Would be better if you would buy now as bitcoin is starting to rise again. But well, it depends on you. I think as long as you are part of the community, the earlier you invest would be better because bitcoin is just getting bigger and bigger. In my case, I just buy bitcoin anytime as long as I have money and still hold them. I think anytime is fine but earlier is better because you'll get more experience faster.

Investing in bitcoin is never late. Goodluck!
