What we can see today is that all cryptocurrencies are highly dependent on bitcoin. If bitcoin price goes up in an observed period of time, then other cryptocurrencies follow that trend and rise up as well. Same action 'to follow' happens if there is decreasing in the bitcoin price on the market.
We know that bitcoin price is at least 10 time higher than any other coin, and for some of them even 100000 times. If coins are chained and attached to bitcoin, as it is now, then small changes on the bitcoin price value, significantly influence on changes for other coins.
So, if bitcoin price value is not stable, and goes up then everyone are happy because affects all coins and all earns. But, in the case as it is now when bitcoin price value is diving toward 2000 dollars, as many predicted, then all coins will go to the point where their values are really low.
Then anyone will say, ok, then now is the time to mine and collect coins for cheap price and after some time bitcoin will go up and you will earn. Yea, but what if bitcoin price stucks at 2000 dollars and even go lower?
There are also many investors that have invested real money to buy coins, and now their cryptocurrency is losing its value, that gives two options for investors: one to sell and take their loses as reality and other are to wait more time and expect their coin to rise. This second option is option that not any of the investors want to deal with because his investment is blocked and there is no possibility for them to use that capital or even try to exchange and play with it on the market.
Because of this, my opinion is that coins must be chain free from bitcoin dependency. So, how to provide this? As one of the possible ways to distinguish coins different politics is to build strong coin community that will make some actions.
Those actions need to address creation of specific coin variables that will create equation which will lead to changes in coin price. Any coin will have own variables determined and created from its coin community, with contribution from the top investors in that coin and members of that coin community. This community of course at any time can make actions and change some variables or equation how to calculate coin price value. Of course this will be restricted just to that coin community, because else there will be easy price predictions, which will affect the coin market.
Those variables, which will be different for any specific coin will give health to coin growth and also stability to the coin market, because investors now will have options to save their investment.
By saving their investment I mean now when coins would be independent then it will be easier for investors if some coin falls, to check trends on the coin market and to invest in the coins that they think has good chance for price to go up. In this way there will be healthy coin market and place when there are basic tools to earn and provide return of investment.
Otherwise, as it is now any chance to earn for investors will be to wait. And does that waiting brings them success to return their investment it is really unclear.
