Yes like me. I really need to save bitcoins because I like when I get old and I had a family I help my children and all my loved ones. So I really want to strive and buy more bitcoins. Because I know in the future I can use it

Well there is talk that bitcoin could reach a value of $250,000 in the future
so some oeople could be banking of gambling on that value being reached.

"Saving" FIAT in bank is counter productive, it will actually devalue over
time because of inflation and depending on the type of account there
would be negligible interest generated on the funds.

Starting a "pension scheme" has had some bad press recently in my
country, commission and fees are paid first, so for the first few years
The installments are not towards the oension itself.

Another thing to consider is maybe millenials dont have enough
disposable income to make a worthwhile pension investment but
enough to gamble on cryptos future....

We all know that, and most bitcoin users are just teenagers (except those who really care about the ecosystem)

But yes, we all know how this works and how it is being done at the moment..

I strongly believe that if its about buying crytocurrency for retirement purpose then i will advice buying bitcoins. I am not too surprise about the fact that millionaires are shunning the traditional banking sytem. The reason is simple, the returns from investing your money at the bank even for the entire working years cannot be compared to investing for some few years in cryptocurrency if speculated well.

Since Bitcoin has become mainstream, i'm not surprising those teenager teaching by their rich parent to invest on this.
But i would be agree if even though crypto was still being new, but there are still many chances for replacement technology that more better than this.

investing in bitcoin alongside the rest of your investments is a good thing and you can do that for the retirement not solely choosing bitcoin and definitely not altcoins. @QuestionAuthority is right, it is dumb to choose a new volatile thing for your retirement.
but i have a feeling that they are not choosing only bitcoin for that purpose, it is more like having bitcoin in their portfolio.

millennials might really have a bad impression from the past generation but hearing about this i think crypto really suits their generation very well for with respect to btc its also getting a demand this years. and being able to think of it for their retirement really shows millenials have a bright future ahead with btc.

Its good if millenials start saving money for their future at their young age.and they know how to invest their money that they will use not only in retirement but also to have their own business.

Millenial people should be doing it. It si good for their future. Nothing bad about that
