In traditional slots you pay a coin, and if a certain sequence comes up, you get some winnings. I think everyone will agree that's a form of gambling.
In bitcoin, to create coins, you pay some electricity, and if a sequence of 0's comes up, you win some bitcoins.
Is this aspect a form of gambling?
And if so, is that illegal in the U.S.?
All of the activities regarding earning a bitcoin and other alternative coins are in the form of gambling but not literal, just like in applying a bounty campaign, there is no assurance if it is a good project that will prosper but you gamble your hard work and time to earn.
