Well, you went all-in into crypto market. Next time be more careful about it and don't invest more than you can afford to lose.
The guy didn`t invest anything,he just got scammed.
I don`t trust any exchange platform, even the big ones.
Making a 21,000 USD deposit into some exchange platform is a suicide.
Maybe the OP isn`t scammed and maybe Kraken are experiencing payment system issues.
Let`s hope so.
