Is there ever a right time? Asking if it's the right time to invest in bitcoin actually means there is also a wrong time to invest in bitcoin because right can't exist independent of wrong. Anyways in my opinion the best thing is there is a better time to invest in bitcoin.
Now bitcoin actually started from a coin with zero value to the biggest crypto currency currently worth over $90k . During the overall bullish trend of bitcoin price there were also a couple of drawbacks along the way and those were better or the best times to buy.

Bitcoin enthusiasts still sepeculate bitcoin getting to over $200k within next year and with the momentum that took us to over $100k this year it's very much possible. And that simply means now is a better time to still buy. It's just a matter of how long you are willing to HODL and what price you feel is best for you.
