Is my Iphone hacked? Virus, Malware,etc?

Yesterday Morning, I receive a text in "Messages" app about banking, I did not clink the link to the website, but only read it and click the next text bubble "touch to load preview " after it show an image with or without the name of company or others things and under it show bit.do (after I pressed it without clicking the link).

After that I got too curious about some similar message I got before, I did the same thing but this time about a reward from Cotsco and then I clicked the link which lead to safari, but nothing appear, only a blank page. I got a bit carried away because I did twice the same link or even refresh it, but still appear a blank page. Only a series of number and dots appear in the link. The series of number and dots is the same as the link after I click "touch to load preview".

After that I delete it both message and also delete the safari history and clear it, but I still don't fell safe and I am scared if my phone is being hacked or being watched, controlled, malware, virus, etc.

I did some research about how to fix the problem or to know if my phone is hacked by several signs to see if one the problem appear (ex: battery drain faster, phone in high temperature, sudden high storage used, etc), for now none of them happened, but I still don't feel safe.

I used my Wi-fi when I click on these, is the Wi-fi also affected (I am not the only using the Wi-fi, its actually my home Wi-fi and my family used them).

I never update to the newest IOS and my phone is old.

What should I do? Should I try to meet someone who work in apple for help or find another way?
