Bitcoin could not possibly be more DISSIMILAR from the lottery.

The lottery is a tax for people with poor math skills. Bitcoin is free wealth for people with strong pattern recognition skills. Kind of like a global IQ test where the stakes are poverty and wealth, it's really quite fascinating actually. It may empower many bright people.

The only way to lose in bitcoin is to buy high and sell low. Selling is a choice. You can choose to ride out the lows and wait for new highs, or you can choose to be a moron and throw away untold future fortunes.
