@OP, please listen to everyone who has given you advice here. I don't have to take a look at the website but by just reading what you've said when they've asked you to pay for a tax. It is an obvious scam.
Thanks everyone for your warnings.
Unfortunately, being incompetent, I entrusted myself to the wrong people who pointed me to these sites.
Now, you have to avoid those people that have pointed you to that scammy website and you're free to ask here once again about anything about crypto just to be sure.
