I don´t know if these HYIP are ok for others. I mean online. But they disspaeared for me.
I would tell you two:
trusted profit HYIP or trustedprofit.com
and HYIP lanner or lanner HYIP.

There was another one in which I think it bases on Denmark currency but I not rember it.
trusted profit brought a psswword problem and disspaeared afterwards like 2 months then.
And HYIP lanner scam me due to an update.

Well I invested in each one a dollar.

I think that one HYIP give me something. It was called emotion HYIP or www.emotionhytip.com but it seems that is not online anymore for me though.

Well you know something now.

Best regards,
Me.
