Don’t let the insults get to you.
But yeah, obviously, the more capital you pay in, the more “credible” your company looks. The whole concept of limited liability means that if your company capital is X €, the creditors can only get the X € (unless you do something stupid, see https://en.wikipedia.org/wiki/Piercing_the_corporate_veil).
The fact that the minimum capital amount is so high in Germany is bonkers to me.
