I guess you can exchange to other coins but they are worth almost nothing right?
There's your answer.. For some it might be worth nothing, but for others it's a nice amount, especially for those playing with playmoney.
165,504,332 PLAY for example is worth about 0.03 BTC. And to hit full PLAY jackpot you have to hit jackpot with a profit of 50,000 PLAY, which is worth "only" 1000 satoshi. Not a bad deal imo.
Yeah that is great deal some how, use only 1000 sat to get 0.03 btc but how an you even get this play money from the start. Let say if you have a btc you can directly play with it. But to convert btc to play money, I do not think that it is really wise idea since play money can be used only here? And you can't do anything after you convert it to playmoney
