Buying Exact match domains

[Sach_nyc]

Hello Experts,

I am new to seo. I have just noticed that around hundreds of great domains matching exact keywords related to our industry is available to use in new gTLDs that are being released in few months. Would it make sense to acquire these domains to get leads for our business? How useful they can be? Can I develop say 100 micro sites on these keyword rich domains to for seo or business benefit?

Please suggest.

Thanks
Sal
