First of all, you should tell us how you going to receive the €, as elmanchez points it out already.
Secondly, what coin you will offer as collateral. I can't imagine that you will give parts of all the coins mentioned above...
And then what % of interest, since you say 20% (4000€) but you write that you repay 5% (1000€).

Sorry, but to be honest, I think that you either trolling or trying to phishing things...🤔
