Thanks everyone. I was wary and wanted to check.

As part of some discord cryptocurrency server giveaway, I apparently won a bit of bitcoin on this website https://bitumb.com. However, I can't find any information about it. Does anyone know whether this site is trustworthy? I was able to use the promo code in the giveaway and it says I received the amount of bitcoin, however, it's also asking me to deposit at least 0.02 BTC before being able to withdraw anything.
