Firstblood, Mobilego and Etheroll are all solid projects which are highly undervalued. You can do some search and you will find out these project have practical applications and are (will be) able to generate profits.
"We will publish our crowdsale contract address in advance, minus the last 5 digits, so there is no chance of funds being sent to an incorrect address." I really like this idea, which could be a very cost-effective way to prevent the potential website hack loss.
It seems that Voise performs good in https://icostats.com/roi-since-ico using ETH as the base currency. With a working beta, I believe Opus will be able to perform better than Voise.
Heard the news about the listing effort on bittrex, which is really encouraging. Recently there are rumors that some of the liqui accounts has been hacked. Listing on a secure exchange like bittrex will definitely make a big difference.
Glad to see this project has a working product already, which is pretty rare recently. Building a wi-fi sharing network is definitely of high interest.
I still support Ethereum, since there are some working dApps running on it. And more and more interesting projects are going into beta phase in this year.
