Back in 2013, I got interested in the hype a got a bitcoin from Coinbase.  Thinking I was being extra cautious, I created a "paper dice wallet" by rolling a six-sided dice 99 times per the instructions at bitaddress.org. 

From their website :  An important part of creating a Bitcoin wallet is ensuring the random numbers used to create the wallet are truly random. Physical randomness is better than computer generated pseudo-randomness. The easiest way to generate physical randomness is with dice. To create a Bitcoin private key you only need one six sided die which you roll 99 times. Stopping each time to record the value of the die. When recording the values follow these rules: 1=1, 2=2, 3=3, 4=4, 5=5, 6=0. By doing this you are recording the big random number, your private key, in B6 or base 6 format. You can then enter the 99 character base 6 private key into the text field above and click View Details. You will then see the Bitcoin address associated with your private key. You should also make note of your private key in WIF format since it is more widely used.

So I wrote down the original 99 rolls as 1330540124221 and so forth.  Then, in a stroke (of genius), I transposed some of the digits (i.e. moved three consecutive digits to another location in the string of numbers) to obfuscate them, thinking if some sophisticated attacker were to gain access to my dice rolls, they would be unable to spend them.  Maybe I was too paranoid.   I've forgotten which digits I 'cut and pasted' and how many ( I strongly think its 3 to 5).  I actually kinda remember the area where the cut happened, not the paste.   How screwed am I?  Any chance to recover this bitcoin?
