First, i dont consider Citadel, JS, etc "fintech" because they are not in the same line of work.
" Fintech, a portmanteau of "financial technology", refers to firms using new technology to compete with traditional financial methods in the delivery of financial services. "
This is NOT what people like CIT, JS, etc. do.
So maybe FinTech is being hit very hard, but from what i hear Cit, JS are doing just fine (no real layoffs).
