First Bitcoin Trade was in 2010 , 2 Pizza for 10,000 BTC by Laszlo Hanyecz. I saw him some of pod cast , he don't wants to talk to that incident. How cheap was Bitcoin that time.
In just 15 years Bitcoin currently Holding $85,500 (at the time of writing this post) price. By 1 BTC you may able to buy luxurious real estate some of your country, A Tesla Car, even you can stay 2 nights on Burj Al Araf. Everyone has accepted bitcoin to worthy of a investment atleast those who know about bitcoin.
So you're holding Bitcoin right now .What you wants to buy with your Bitcoin in future? Maybe fast forward next 20 year later.
You're not just buying blindly right. What your vision with Bitcoin after 20 year later
I might not want to buy anything in particular and just want to have a financial leverage in my later days and possibly something to pass down to my generations without governmental interference and to maintain a low profile as against having real estates and other properties to my name that attracts undue attention and possibly undermines your safety and security.
People invest for their retirements so they can live a comfortable life at old age, bitcoin investment can serve that purpose and that is why I am heavy on purchasing it because I want to enjoy its benefits much later in life.
