From these three I will choose airtoken because they have good strategy of marketing and then they also have promising projects.
However, I will only invest in two to three projects a month and for now my quota of investment is full with social ICO, electroneum and coss.io So for now no more investment but I can suggest you to go with social as they are going to be launched on the major exchanger very soon and you can expect that to happen in the November month. If you are excited enough then you can invest the money from the yobit as they are avaible over there. That would be good investment.
