This is actually a bit crazy to say, couple with what requested and again saying you can afford to lose that 0.05 btc it is like trying to say that you have sufficiently enough to foot the bill but you are just trying to fool around here to keep discussing with you. To me there is no need for this topic if you think 0.05 seems pretty too poor for you to lose why don't you clear you tuition fees without having to gamble to increase your btc to 1.7btc knowing to well how gambling works.
And besides there is every possibility to easily sweep off your account since you are placing too high stakes, 0.025 for just a single game, why not go lower like 0.0009BTC to win 0.0015, with this strategies it could difficult to easily empty your account just like that.
