Considering the supply vs global population = 0.003BTC per person to go around.
Then other factors like not all 21 million will be in circulation due to lost wallets/deceased hodlers who never informed anyone where their seed is, and also an increasing global population and future generations who all want in.
Do you think 0.1BTC will be like owning a mansion?
I did not understand exactly what you saying, are you saying of distribution of 0.003btc as you listed will it serve to do what? I fine it difficult to understand, but the down side i think i understand it, 0.1btc is like having a mansion in my side because bitcoin now is like gold before.
