There is activity on their slack channel. Devs have some troubles related to real life, but ColonelClink said that development will be continued in a week or two.

I had the same bug, but after I entered he wallet address second time it seems to stay after logout. Not sure it wouldn't happen again.

So, why only 51%, why this weird number exactly?

I think at least doge already has really big market cap (300 million), which, of course can grow, but not that much.

I observe this market for three years now (however started trading only few months ago). What I got from my observations - I think fiat economy schemes aren't applied here. Yes, we see huge pumps once in a while, but usually prices during pump predict the future prices (it may happen much later, but eventually the floor will reach this level). I'm not talking about scumcoins here, which are getting pumped only to be dumped afterwards and abandoned by developers after they made some profit of it. But decent coins usually don't drop that significantly (maybe in 2013, but at the end of the day market reached, and overgrown even that level).

I believe at least half of the current coins on market are just re-branded version of other successful coins. But some of them still may have decent development and community support.

Any news on project? I really hope it wouldn't die halfway to the top.

Wow, someone who actually analyzes the situation and don't whine about inevitable doom of market crash. Glad there are still people like this left 

Do you plan on selling OTX on bittrex or other major exchanges in near future?

Agreed, it would be great to see WYV on at least a couple of minor exchanges (such as novaexchange and livecoin).I beleive it would generate decent volume for current coin development stage.
