Thank you for your suggestions friends. I read all. You clarify me many things. I think I will use https://localcryptos.com/  to buy 1eth first. Crypto is a larger world than I thought.
You said about Bitcoin Atm. I didn't know it yet. It sounds interesting. I'm going to explore it now.

Hi all, I'm new to crypto as recently I have free time on the internet and see an ads about it. Google brings me here, and medium, some crypto websites too. I want to own some coin and try to invest. The only way to buy crypto is credit card. I'm confused that why I must provide my identity, passport number and image of it, and photo of my face. I read and know that crypto is anonymous, why I must kyc to buy coin?

Thanks for your suggestion guys. I try chrome mobile and rotate my phone to horizontal, it has better look. It's still hard to move around forum, threads, posts and pages.

Thanks. The add-on developed by forum member right? I see an old account member said that he would not risk his account to use the add-on.

Hi all. I surf forum on my phone and it does not auto scale. It's very hard to read. Seems that forum does not have mobile version?
