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
I think that the risk is not too big if we don't use a big amount of bitcoin so we can keep the rest amount for the next bull run that will happen soon. So I think although we are losing money in the lottery, we don't lose too much money because we still have the rest bitcoin. It will differ if we use all of our bitcoin to buy lottery because we want to hit the jackpot.
