As for investments in crypto, I don't believe any crypto deserves any "investment" at all, understanding that "investment" to me is supporting a project from inception to consolidation. If any, it would be BTC and, perhaps, NXT because they are quickly (NXT) consolidating and their exchange is growing in volume every day exponentially. But I don't give investment advice not in crypto and definitely not for free. I can tell you though that I trade, rather heavily, in a bunch of coin projects... including NXY and XPY and a few others. I have a weak heart for Solarcoin, for obvious reasons, but I am not sure that "investment" will ever pan out.
I doubt you would take away anything of value on what I just posted, I chose to ignore your request because I don't think you should be influenced by me or anyone else, nor should anyone. This crypto "scene" is far from being ready for investment, so risk your money on your gut feeling if you feel like. If you do it after deeply researching the tech, you'll probably support very valid projects but also probably you will lose money rather than make money. So, I'm afraid, you are on your own.
First of all, thanks for a valid answer. I like when the discussion goes in a civilised way and we have both 'pro' and 'against' voices that are clearly stated and backed with arguments. No spam, no fud, just the arguments. That is what exactly is needed, as most of the altcoin topics seem to me too much religion-based stuff, where you are either all in and accept it no matter what, or you must GTFO, just because you have different opinion.
Now, regarding altcoin market. I am fully aware of the fact that this is a highly speculative market, with a lot of volatility and risk involved. I have dedicated part of my portfolio exclusively to that and thus being aware of the underlying risk, I look for several coins that seem to be the opportunities. Having 5-10 candidates, with just one living to the expectations you make up for the losses on the others. You may also lose all, that risk is counted in.
As for VIOR, it is one of these speculative positions in my portfolio, exactly because of its potential to grow. One of the very few coins recently, backing up the coin with something that is interesting and bringing something new on the table. On the other hand, we have all typical problems of altcoins, with PR being badly abandoned and user support being far from optimal. still, I think it is not completely bad project after all and that is why I am here.
