Very easy to set up.
Check mine, and other scripts as to whether or not they steal your coins
Press CNTRL+F to search the code, then type in /send or send to check if the code will send your coins to someone else's wallet.
WARNING! My script cointains multiple send commands, the reason for this, is, that with the new layout the only way to "send" a bet is to use the send function.
But you can take the time and check each one to see if its a send for sending coins or a send for betting, it should be fairly obvious.
Some scammers are a little more sneaky and try to hide a external javascript that will do the same thing as /send or send. Press CNTRL+F to search the code and type in .js
