I think you should invest in
RPX
QLC
SONM
Reason: check them out and research a little and their all time high prices.
Upto 20x is possible.
And invest in CPX.
Again check them out and you would be drooling to buy them
Any reason for you to anticipate this. Personally I would not invest in old projects because it really does not have the potential for future development. If you want to invest in new projects and get the confidence of investors and developers, then you should choose because of the ability to earn very high profits.
