I am currently applying for graduate schemes and am in the dilemma of whether to mention that I trade on betfair. I was therefore wondering if anyone has experience from mentioning trading on betfair to potential employees?
I am applying for data analyst roles so what I do on betfair is very relevant especially as I specialise in automation/excel/SQL e.t.c. But as soon as I mention gambling people think I have a problem

Anyone got any tips on making it look impressive rather than a problem?
