You will end up in JAIL
since bitcoin is decentralized i doubt this, but if it is significant and he leaves footprints (like this thread) than definitely so.
So what? Even though Bitcoin is decentralized it doesn't mean he will avoid the jail (in the case he get caught somehow).
Bitcoin is not recognized as FIAT currency in almost all countries, so in the case you steal bitcoins you won't end up with criminal offense but in civil offense.
Example: you steal 10 smartphones from 10 guys it's the same as stealing 10 bitcoins from 10 guys.
I agreed that bitcoin is a decentralized currency but OP might not get away with fraud in case he does any because bitcoin transactions are now traceable.
Do you realize that tracing transactions is hard as hell? If OP moves or doesn't move bitcoins from a specified address you still can't retrieve his informations because any IP or other sensitive data is not stored on the blockchain. That, expecting OP is using a client like Bitcoin Core and not online/web wallets (eg. blockchain.info) since they store your IP etc.
But in the case OP transfers funds to a localbitcoins address (ad example) then organizations such as SEC would be able to find out who you are just because localbitcoins is forced to release the users informations to them, it's the law yeah.
I hope you get my explaination
