HI All,

So, i invested in the ICO,
I made a ton of money however now i have no idea how to prove i purchased the NEO,
I can;t remember the bitcoin wallet i used/address i used.. At the time i only threw in a couple thousand dollars, not enough for me to have thought to remember to keep a good record.
I only know my NEO ICO receiving address. Is there anyway to prove or find out which BTC adderss i sent the funds too in order to get the neo using just my NEO recieving address?
I need to know for taxation records.
If anyone has any ideas,please let me know.
I hope you all were succesful with your NEO investment like me,
Thanks
