I am sure not only extending the token sale won't attract any new investor, but it will frustrate people who were supportive of Pointay before. Why should some one invest in a token sale that won't be ended till 2 years later? Why should people freeze their money for two years while they can use their money in different options in these two years? Why should people invest in a token sale that there is no certain schedule? Now the team should have focused on development of the project not crowdsale.
I think the token sale is already failed and any attempt is useless.
