Can i trust a company working in mutual funds which offers 25 % benefit each month?

there's a company working in mutual funds in switzerland which offers 25% returns on your principal investment every 30 days for ever. Does it sound logical? shall I invst some money in it?

No. Sounds like a typical Ponzi scheme where new investors are given older investor's money. Don't be around when they stop playing the music and there are no chairs to sit in!

At that rate you will become a trillionaire before you die.

Yes, I am a member since August 2006 and have invested my money and still getting returns of 25%.

possible
try with some amt
& kepp on adding after few years

Sounds great ! Within 4 months you can get back your initial investment. However it might be a trap. You will get back the returns within 4 months. People are greedy, when they see the returns they will pump in more money into the scheme and eventually see that they have lost all the money. There is a saying. "If it is too good to be true, dont take it"

This equals about 1,000% a year. If you invested $100 today, in 2 years it would be worth about $207 million. Sounds reasonable to me. Seriously, sounds a little ridiculous doesn't it? The only way this works is if it is a Ponzi scheme, and that is immoral. You are anonymously stealing money from people.
