Absolutely!!!
Bitcoin is one of the best assets one can have in this century. Instead of depending on fiat currency and fixed deposits, why not have Bitcoin, have gold, have a business, and many other assets available.
All these can give high returns in the long run.
I agree. It is a good asset, a guarantee that you will have money even if you don't technically work. However, having it alone is not ideal or advisable. It is better to have other assets like land which is guaranteed to have good rates. We can think of bitcoin as a sub asset that is good for financial assistance when we get old and are more focused on resting and enjoying life.
It would be a big omission if we don't add bitcoin to our retirement savings as it is considered the most profitable asset by far. But let's not be subjective that it's not risky but diversify our retirement assets into many other assets, don't be too greedy and just focus on bitcoin. I am planning on retirement savings of 30% bitcoin, 30% gold, and if I have a substantial amount of money in the future, I will hold real estate to complete my retirement portfolio.
