Investing into Bitcoin is good and for the time being, we can actually make a ten year speculation on the fact that it will still remain a valuable and profitable investment ~
If we learn the growth of Bitcoin price, it always shows the chance for good profits. We already experienced few bullrun season, Bitcoin price always increased significantly from one bullrun season to another bullrun season. We even don't need 10 years, it is enough to hold for 4 years. The bullrun season has 4 years cycle. We only need to follow this cycle to ensure good profits.
Yep, Bitcoin is a speculative investment. But with the fact of it has 4 years cycle, it is actually not a very speculative investment because we know how long Bitcoin to increase its price.
Is it wise and realistic for someone in his early twenties to set up Bitcoin as a retirement plan such that he continues accumulating Bitcoin from this time till he gets to his retirement age?
Why not to have Bitcoin as the asset for the retirement?
If I have enough money, I must buy some Bitcoin when it is in the bearish season to hold for my retirement investment. It is already proven to give great profits for any investors in each bullrun season. I just need to keep it on my private wallets and wait for the bullrun season every 4 years. This is an easy thing to do when I've retired from my jobs.
