I also think that Bitcoin is simple and can be had easily on all of our smartphones.
And this we don't need to carry dozens of kilograms for weight, even this digital asset Bitcoin can only be seen on smartphones.
If we refer to the gold we have 3 kilograms which is equivalent to 5,000,000 USD, then Bitcoin only needs 5,000 Bitcoin to reach 5,000,000 USD and does not have a simple weight and can be taken away easily using a smartphone.
