What will do you do when ICO end?
I don't know what you mean or want to know.. But you should know that the project is going to continue development even after the ico end... The ico funds will be utilised to develop the project.
And of course they will come on exchanges and you could still buy there but not for the same price and not with any bonus at all.
Speaking of exchanges ... Did they already announce some exchanges that will list the tokens after the ICO?
I know what I do after the ICO, holiday. I will sell my power from the solar panels to someone via the bittwatt platform and enjoy my passive income.
That sounds pretty cool, but how do you mean, sell your power from the solar panels? Solar panels on your roof?? Very cool if thats the case, the future is coming

Yes, that's what it means. If you have solar panels on the roof, you usually produce more power than you consume. At the moment it is usually sent free of charge to the electricity grid of the country.
With Bittwatt you can sell this generated electricity on the electricity exchange. This can be very lucrative, I will definitely do that too
