Bitcoin is going to rise to 1.000.000$ when it won't be able to be mined. Therefore now is a good time to buy.
You obviously don't know that according to calculations, the last block of Bitcoin will be mined in 2140. So it will be a little difficult for you to verify the correctness of your statement. But if you buy Bitcoins today, there is a chance that your great-grandchildren will thank you for such an inheritance.
Whether bitcoin will rise to $1m or not is not something that someone should be talking about now because no one can really tell what the future will pan out for bitcoiners. However, the 100k ATH is not the highest it will go as, the last block of Bitcoin will be mines by 2140, approximately 116 years to come. None of us here today will still be alive by then, before then, bitcoin will most likely be the most valuable asset in the world attaining more than $1m.
If you have a bitcoin asset today, you can decide to hold it some more time because based on my calculations, if it will take approximately 3 to 4 years for bull run to reach its peak, then there will be a total of over 29 to 30 bull run seasons before 2140, one can't imagine but to say that Bitcoin must have hit very significant appreciation level beyond expectations.
