Bitcoin is not a get-rich scheme, many people in this community has less than 1 BTC.
It takes hard work, either by trading, working, developing etc to earn bitcoins.
Many still expecting bitcoin to go up to $100k per coin. Check out the speculation section.
Yes, not impossible.
There are two ways to reach that:
1. World wide adoption of bitcoin, we are not anyway near that, there are political/economic politic powers working against that.
2. Complete collapse of the world economy, which will result in a dollar becoming almost worthless.
The later option is imo the most realistic way for bitcoin to reach $100k.
But you have to remember that the buyers decide the market price.
In order for 1 BTC to be worth 100k, then
must there be a buyer willing to pay that.
There has to be "someone" willing to pay big bucks for bitcoin.
Will you pay 100k per coin?
