this because the whole pos thing would otherwise be a dump fest, that's way every pos coin out there has a bad value and always will have
the mining power give somehow a value to the coin, or at least make so that the coin will not be just dumped to death, from those that are mining
I just can't agree with you. Not everybody has the chance (and ability) to mine coins. Many people could be happy with their $2-5 earnings from staking and there is a good chance for them to hold their coins. Thus can lighten the sell pressure and could give the possibility for the coin to grow in a long term period (if things are done right).
The people that dont like pos are miners that dont want the general public involved in their tech game of mining which means more money for them.
Pos gives the opportunity for the average person to mint coins. They dont have the time nor the interest in the mining pow process due to having a life, making money at businesses etc...
Furthermore, the majority of people confuse a pos of 5% with a savings account earning 5% from a bank. Keep in mind that you are getting 5% of minted coins that range from pennies to a half dollar and more. What this means is that your stake value is more like 25-50% value in dollars.
