You should rethink your crowdsale incentives and marketing.

Having concurrent mining rewards during a crowdsale gives small investors less incentive to give and more to mine.

Ethereum price was on a bear trend lately which shook some investors confidence.

Most importantly a total lack of promotion or hype in the months precedeeding your crowdsale and lack of on going community engagement during it. I'm still waiting on that reddit AMA.

I actually don't understand fully the incentive to hold blockCDN after 3 years from start of active service provision since you stop paying dividends to holders after then. It usually takes 3-5 years for a service to build a sizable

What do I gain from holding blockCDN for > 3 years? Do you expect the tokens to appreciate in value? Will there always be a fixed total of tokens or will you increase token cap in future to reduce prices for customers and ensure your profitability and the expense of your early investors?

Perhaps extend the deadline or actually promote actively in threads with ethereum users, investors and audiences e.g. the ethereum or ethtrader reddit sub where plenty of potentially interested people hang.

Your promotion on these threads has been lacking.

If the crowdsale fails aside from refunding the ETH will you:

Do a debrief?
Seek a consultantion on why it failed?
Continue the project?
Seek investment elsewhere?
Relaunch the crowdsale?
Tweak the incentive structure and marketing if crowdsale is relaunched?
