No way, because if the 0.002 BTC that I spend today ends up being worth $100 next week, next month or next year, I'd be very upset.
0.002 btc will be worth if bitcoin price increases because we don't know how higher bitcoin price can reach. I think that is why some of us prefer to buy lottery with altcoin because they can use bitcoin to purchase altcoin and I am sure that they will get a huge amount. But who knows, by buying the lottery, we can get lucky so we can win some money

You should expect for gain though keeping in mind the reasons why should Bitcoin gain value till May 2020. But isnt it a risky investment to use your Bitcoin and buy some lottery ticket? The odds or winning when it comes to lottery are very low and your probability of making the money is one out of 175m according to statistics of previous lotteries.
