The main issues I see:
1:Unlike trading shares, stocks and bonds.... where more companies, the better results. Alt Coins Traders are trying to cut each other
I was on the URO Coin forum and noticed XCoin Dev. logging in and trashing the URO Coin. This childish behavior needs to stop and to act more professional.
2: Banking the Alt. Coin to international Companies or products is quite unique and sells.
3: Please no more "privacy" transaction coins
Hope this helps
Here's my take:
1. Unlike trading shares, stocks and bonds.....where more companies provide value through their products; most alt coins provide nothing. Most of them try to be store of value. With bitcoin and litecoin around, why would anyone bother with them. Yes, there are some innovations like MSC, NXT etc but certainly not the high valuation they currently claim.
2. I am not entirely sure what the 2nd point means but I guess you are talking about innovation. There is next to 0 innovation in altcoins. They have yet to think of something Satoshi hasn't (and by that I don't mean some new algo - PoS, x11, x15, nscrypt etc) but something really makes them apart from them being more than a store of value.
3. It is rather conceited that most coins think they provide "privacy". Bitcoin was supposedly anonymous, until it became famous and it was no more. The whole "privacy" thing is like "Mac has no virus" claim. Under that claim fact really is: User base and acceptance of Mac is way lower than Windows so many virus writers dont bother with it.
Similarly, coins with low following (ie not rivalling bitcoin) can claim anonymity to their heart contents. If they ever reach the popularity of bitcoin, they might even have a worse privacy implementation than bitcoin.
