How did he cheat? All the transactions were confirmed! You stole his money. He didn't double spend any of those coins did he? Go back and look at those 10 transactions. Tell me where he double spent them. It's clear that you are both non-native English speakers trying to communicate in English...mistakes happen! Did he say "double spend" when he meant "Sent unconfirmed?" From context, it certainly seems like it. Therefore...you stole his money. And you're bragging about it! That's really fucked up.
Stealing people's money that's sent from unconfirmed transactions is wrong (also, you know, illegal). Tons of people send off of unconfirmed transactions because THAT'S HOW THE BLOCKCHAIN WORKS! You need to refund this guy's money immediately and then shut your site down because it's become glaringly clear that you are in way over your head and are making mistakes...either intentionally or unintentionally...that result in stealing people's money.
You can not see double-spend or not after confirmation!

our script full-automated and catch double-spender!

Verification of bet
1. The crazyBtrade.com use real time data from exchange BTCC.com (spot.btcc.com),
The buy price BTC/CNY, volume and time stamp is perfectly out of our control!
2. Provably HASH value is hash SHA256 of BTC/CNY buy price : TIMESTAMP (unix time stamp, unixtimestamp.com) : VOLUME : TXID ( bitcoin transaction id of your payment).
For example:
TIMESTAMP=1475569996
BTC/CNY buy price=4069.32
VOLUME=182820.55980000
TXID=de1f78ed0e2fdb557458a4af1aecf17d73b06df8ed51cd0d14919dcf995b4175
Seed value=4069.32:1475569996:182820.55980000:de1f78ed0e2fdb557458a4af1aecf17d73b06df8ed51cd0d14919dcf995b4175 (BTC/CNY:TIMESTAMP:VOLUME:TXID)
Provably HASH=
sha256(4069.32:1475569996:182820.55980000:de1f78ed0e2fdb557458a4af1aecf17d73b06df8ed51cd0d14919dcf995b4175)=
1a6e1f9e27d5e8e8a2014a3c56bfd6ca975a72580aa4b1c8670bac344ca9c1f0
3. If you have choosed EVEN bet
and the first digit of Provably HASH is EVEN then you WIN 198%. Winning = bet amount X 1.98
If the first digit of Provably HASH is ODD then you LOSE.
4. If you have choosed ODD bet
and the first digit of Provably HASH is ODD then you WIN 198%. Winning = bet amount X 1.98
If the first digit of Provably HASH is EVEN then you LOSE.
You can always see the same result of sha256
