Not an issue at this point.
Any plan to continue develop this coin in future? Is has a good name and history here..
Not in any conventional sense of the term “development”, no. But ...
I'd argue that the history is uninspiring. The emission phase is complete and block reward is basically tx-only. Trading is minimal, wallet is in “maintenance mode” on Yobit and as noted above, delisted from Bleutrade.
Also, not a good choice of name by jp OP, there was already a promotion-redeeming “smart electronic coupon” called VCoin, offered by a company registered in HK. They made a trademark application for VCoin in the US last year, might even have been granted by now. VCoin is basically obliged to re-brand completely - like Darknet re-branding to PIVX. Any conventional development would have to acknowledge the unexceptional nature of the technical aspects of the coin and have to be positioned in such a way as to render this aspect relatively insignificant --- the fact that there have been 3000+ launched altcoins testifies to the difficulty of this task.
VCoin is a totally blank canvas, the OP abandoned the coin almost as soon as the code was made public. In the complete absence of a “public vision”, I've felt free to adapt the coin to be a public work of art and, working in my own branch, am in the process of decorating it with a few imaginative notions that I conjured up, based on some reading I did into some of the less-frequently considered aspects of a peer-to-peer networked cryptocurrency.
It's very much a labour of love. As a public work of art, there is nothing to interest “investors” - which is why it's not an issue that Bleutrade delisted the coin. It's difficult to see how an untraded, emission-complete, tx-only, SHA2-256D coin going to be of much interest to the altcoin mavens of bitcointalk, especially when there are so many other much more promising alternatives.
As for the quietude in this thread - I'd rather get on with the art than yak about getting on with the art.
If you're interested in art rather than money, PM me and I'll elaborate further.
Cheers
