New to Bitcoin, new to Kraken, feel like I got played

I just invested a few $$ into Bitcoin using the Kraken app cus it was advertised as one of the lowest fees app out there and they were also running a 3% match on any deposit last month.

Now the fees aren't little at all (or idk if other platform charge even more) also I bought when btc was around 68k but got charged at 69k, I also had to subscribe to gold to lower tremendously the fees.

Today I tried to check what would be my fees if I were to sell, not only there's like a $100s fee, the spread on btc is like a $1000 lower than what it really is when selling.

Also the app sucks, it's laggy, has to be refreshed almost constantly and most of the time doesn't ask for authentification.
