@fx - From your post "Invest with me", you already have 500k - and you are looking for 500k more to actualize a certain unspecified investment. From this post, it seems you can make 35% every three months. Here is my advice - free of charge.
Invest your 500k at 35% every three months. This is how it will play out
First three months:
35% * 500k = 175k
New Principle = 500k + 175k = 675k
Next three months
35% * 675 = 236.25k
New Principle = 675k + 236.25k = 911.25k
Next three months
35% * 911.25k = 318.9375
New Principle = 911.25k + 318.9375 = 1,230,187.50/=
There you have it. Your 1 million plus 230k "pocket change" in nine months! Unless of course there is no 500k nor 35% every three months.
Never count on making a good sale. Have the purchase price be so attractive that even a mediocre sale gives good returns.
