Of course you shouldn't.
If you were to here him (well, me) you'd ask for my CV -- if not an interview also.
And if it was like "developed some random toy stuff" you wouldn't hire me to develop a money exchange playing with other people's millions of dollars.
And if you were to assess if you will put $10,000 in a financial online service made by me, my past work in the area, my general competence would be quite important.
Else, don't be surprised if you lost it all. The chances were way higher than if you had put that money in Citibank, you just ignored the signs.
And for me, not giving the impression I'm a 20-something script kiddie with a fancy handle would also be quite important. I mean, it might be prejudice, but "Ives, Rockefeller and Berstein" as a financial service just feels more secure than "$uper7eetMoneyMakah", "LuvFlamingoes" or "MagicalTux".
How do you feel about "Bear Stearns" or "Lehman Brothers"?
I'm the last person to defend Karpeles' competency, but his internet alias has nothing to do with it.
