Mining top coins are not that cost-effective but mining a coin early which we believe will have a great future is a whole different game.
but in case of PoS you need money to make money.
Actually I don't see any problem with PoS coins because in real world itself the principle works that real is supposed to be getting richer and the poorer will get poorer and while you like it or not that's how it works so I see no problem if the same applies to coins.
That's not what I wrote. I'm talking about Bitcoin itself as a so called investment. Miners are the only ones who make money. They have not invested in Bitcoin. They have invested in mining hardware. They mine Bitcoin because people are still fooled into buying it.
While you have a point but let me try and explain you, people use bitcoins for various tasks that can't be achieved otherwise so they buy bitcoins and miners are getting paid to mine those coins so everyone is at benefit and that is what the power of an ecosystem is and why it exists.
There is no other reason to mine it. It has no utility. It has value because people have put money in it, but it's still a liability. Liabilities cost money. They just don't make money.
But, if you look into most cryptos, they are lagging with utilities still they manage to have higher value due to speculative reasons. Based on speculations, investors and traders continuously pumping it. If people look for a coin with utility characteristics to mine, then probably they will be left with very few options which again goes against them as heavy competitions in mining leads to industry like mining which is exactly happening with BTC mining.
