I have voted for 100-500 bitcoins but i see many people voted for over 1000BTC because it depends on currency of that particular country.
But according to currency in my country you will be a millionarie for sure even with 2-3 bitcoins specially after 5 years when price of bitcoin would be more.
I will also go for the same amount as yours. Actually if I could get that amount, even before 5 years I can be very sure that I will use it for diversed investments that can yield very big returns for me which make me a big fiat millionaire.
How I wish someone can just say take 500 bitcoins since that what you voted for, it will be like is this a magic or am I am just dreaming.
You are just dreaming though, who would able to posses such amount of bitcoin as you mentioned if you have then for sure you would be really a millionaire in upcoming 5 years, hence we already know that bitcoin would surely increase its price on those years but the question is how much bitcoin do you able to save up.?
