A good amount with 0.1 btc is possible, but hard to happen, I think it's better to don't try anything risked.
fast high bets is a good idea though I do not prefer Dice games because it has high risks and more likely they are random and mostly dependable on your luck, and I don't prefer gambling either, you better just save or learn to trade, but if you want gambling, I cant stop you. Try sports betting where you can analyze some good teams where to put your bets. It may need some patience but it is a high chance of winning.
While you are doing some sports betting you can also try doing some strategy, you can try martingale and fibonacci there. As I said, it really needs patience so good luck.
