I'm starting to like full POS coin, just because they avoid all the miners dump in loss to destroy the market. But I'm getting pretty diffident in investing in ICO coin, one is good hundreds are shit. It's an hard decision, at least this one has a nice graphic, many times it's more important than the product itself.
Miners protect the network and create trade volume by selling (if there's buy support of course). Mining also prolongs the distribution of the coin if the PoW period have a healthy duration and not just throw all the coins out there at once.
And miners usually don't sell their coins cheaper than what it cost to mine them which creates a floor price.
As oppose to mining, generating PoS coins cost absolutely nothing therefore they are worthless.
The only value these coins have solely depend on how many people a random guy claiming to be a developer can convience to sell his magical internetcoins to, which he just created out of thin air. I can sell you some bottlecaps too, $20 a pop but they are magical and you can even touch them...
And if a coin is mineable then a lot more people will get involved with the coin than a handful of gamblers who don't mind giving money to a stranger and rewarding scammers in the process.
There's nothing wrong with gambling but calling it investing is borderline delusional. If you say things like "a nice graphic, many times it's more important than the product itself" then you're not making a calculated investment, you're throwing money at the wall hoping more would bounce off.
Please also "invest" in playing poker with me.
Besides, traders are looking for profits just as much as miners and if a coin has no prospects of having real world usage both of them will dump all the same.
And realisticly, PoS in crypto is complete garbage considering how short coins last before dying. Like what's that yearly 1% (or even 10%) will do to you when the price will swing more than that on a daily basis.
