I am going to do my portfolio on prosite...its cool.
I have an adobe account, the free one, and after 30 days i think its going to dissapear...What happen next? If i do my web with my own domain, its going to dissapear, or they are going to tell me that i have to pay to keep the web page??
Hello - ProSite is only free with a paid Creative Cloud subscription, not with a Trial membership, which is sounds like you're on. However, anyone can use ProSite for free to create and work on their site - UNTIL you want to publish it. At that point, you can buy it as a standalone ($99/year), or you can get it free as part of a paid Creative Cloud plan.
