I already said what can you do with that money here, so with 10 btc I would cash out 9 and I would buy a house, with 1 I would play poker and slots in my favorite casino.
The bold part is probably why you never will get some financial independence. Smart people never "invest" in things with a negative expected value.
I will never understand why people play things like just-dice or oder dice games. The chance to win in the long run are 49.5% (1% house edge).
You can't beat the house.
Obviously dice game isn't so much his problem as is his vision-less business decision. Something akin to successfully people is that they don't put fetters on their money by using them to purchase liabilities, instead they are invested in assets that turns around to pay for their liabilities.
A scenario likely to unfold after paying for the house and gambling with the balance of 1
BTC, is that the 1
BTC would be gone in no time because he would be playing under pressure as he really cannot afford to lose the money. Then the house would eventually be sold for less, so to chase the 1
BTC and the vicious circle continues.
