Guys please give me some tips or advice if how will I know if a site is a Scam or might turn into a Scam? I always got scammed before from some HYIP sites. I wanted to avoid it.
I think the only advice i can give you is: do your research.
First, search this forum for reviews, then google some more for reviews.
Lastly, look at the site itself: is the whois info hidden? Do they have an address, is their business number real, is their phonenumber real? Some countries have some sort of organisation for webshops, it's allways a good thing if the shop is accredited.
The fact remains that even the most trusted webshop might scam you... So allways be carefull.
I realise i'm talking about webshops... In your OP you ask for tips if a "site" is a scam or not because you got scammed by HYIP's. To tell you the truth, i think close to 100% of the HYIP's are scams, or will turn scam after a couple of weeks/months/years. This is why i concentrated on other sites... I think it would always be a good idear to stay away from HYIP's
