Crypto Gambling CGT Implications

[#1]

What's the CGT implications of these scenarios... I've provided what I understand to be the case....Assuming gambling winnings/losses are exempt from CGT)

Please help me understand if this is right, or where I've gone wrong.

Thanks in advance.

Scenario A (exempt winnings)
/////////////////////////////////////////////////////////
Bought 100 BTC for $1 each. (100 BTC = $100)
Value increased to $10 each. (100 BTC = $1000)
Gambled 50 BTC and lost. (50 BTC = $500)
Gambled 50 BTC and won 50. (100 BTC = $1000)
'Cash out' 100 BTC for AUD @ $10/btc. = $1000 aud in pocket.

===

CGT exempted on the 50btc won gambling. ( AS in they were (re)obtained at $10/btc rather than $1 -- So have no CGT when cashign out at $10/btc )
+
CGT applicable on the other 50 that grew from $1/btc -> $10/btc (50*9 = $450)

So $450 total taxable

Scenario B (BTC won -- appreciates )
/////////////////////////////////////////////////////////
Bought 100 BTC for $1 each. (100 BTC = $100)
Value increased to $10 each. (100 BTC = $1000)
Gambled 50 BTC and lost. (50 BTC = $500)
Gambled 50 BTC and won 50. (100 BTC = $1000)
+Value increased to $1000/btc
'Cash out' 100 BTC for AUD @ $1000/btc. = $10000 aud in pocket.
===
The 'won' 50 are taxable from $10->$1000 ($990/btc == $49500 taxable)
The other 50 are taxable from $1->$1000 ($999/btc == $49950 taxable)

So $99450 total taxable.

\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

Scenario C (exempt losses)
/////////////////////////////////////////////////////////
Bought 100 BTC for $1 each. (100 BTC = $100)
Value increased to $10 each. (100 BTC = $1000)
Gambled 50 BTC and lost. (50 BTC = $500)
'Cash out' 50 BTC for AUD @ $10/btc. = $500 aud in pocket.
===
Gambling Losses/Gains aren't deductible, so CGT will apply normally to the 50 btc. 50btc * $9 profit/each =$450 taxable

So $450 total taxable
