Timo Hetzel, host of Bitsandso and a tech blogger/guy. I'm not all too familiar with German techies. But: As far as I know they let it slip that he knows someone fairly high up at Fidor Bank (and he also lives in Munich ).
We also assume that Rudolf Linsenbarth has connections to comdirect / Commerzbank.
Question is: Who knows more
Well, who would you believe more?
Someone whose daily job is to stay in touch with major bank representatives or a random tech guy who could possibly know someone that works for a not so known fintech (Fidor is mostly unheard of amongst „normal“ people as opposed to comdirect and the likes).
