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
Definitely, why should anyone buy bitcoin out of ignorance. Past event don’t always move in same direction in the case of bitcoin don’t put your all in at once instead invest gradually using the available funds, continue buying bitcoin expecting a better future. Bitcoin market movement is unpredictable basically few are discouraged and it doesn’t make any sense seeing bitcoin growth, personally getting a good investment portfolio should be the plan of every investor.
