How would you define what is to be "rich"? Is it about having enough for living or is there something else that you would be looking to accomplish to be rich?
Is it 1 million USD? Is it 1000 bitcoin? what are your thoughts?
For me it having a peace of mind that you know you can already secure you and your family's future with the money or assets you have right now plus having a secure income or job as your back up. But still hard to define for me how much amount was that due to inflation. What we can buy for $10 today will not be the same thing to buy $10 5 years from now. I think savings is quite an advanced but still will not be enough due to sometimes greediness or unexpected expenses.
