whether any altcoin supported by a business coin prices will go up? How do I know what a coin price will go up?
It depends on a lot of aspects. In no particular order:
1. The coin dev(s) are not in for the short profit
2. The company/ies that back up the altcoin is/are legitimate
3. There's enough circulation (ie: how many people hold it & use it)
4. There are no parallel forks
5. The pre-mining factor (the less, the better)
6. The coin's scarcity
7. The BTC/coin equity
8. The coin's popularity within the mass media.
Not many altcoins have them all. If you find one that does though, please let me know. I want in!
Startcoin point by point:
1. Startcoin was developed as a part of the startjoin ecosystem, and thus is not made for short term profit, but rather as a tool for a purpose. Who the developer is/was is not even important.
2. Startjoin is certainly a legit company that you can buy stock in.
3. StartCoin is circulated and used more than most coins, and not hoarded to the same degree since its used to fund projects on startjoin. One example,
https://www.startjoin.com/ggbradford2015 - a British politician was founded close to 20K$ mostly with startcoin.
4. There are no forks to my knowledge.
5. This may be the only point where you might think its not ideal. I think its better than ideal. Startcoin is 50% premined. The premine is used to pay interest on coins deposited at startjoin, and also to award pledges you do on startjoin. The karma score decides how many coins you get each week.
6. Startcoin is not very scarce, so it can still be had for a good price. Recirculating of coins through the pledge system means that there will always be coins to buy, and no artificially high price to pay.
7. Im not sure what you mean here, but the current market cap of about 500K $ can not be considered high given that close to 1/20 of the market cap can be involved in one single project.
8. Startcoin certainly has the best publicity potential of any coin besides bitcoin. It's used to fund politicians, it has two well known TV stars from RT leading the publicity campaign (you know who), it even has its own TV-shows
