This site is really becoming quite useless. You guys should give up this mud slinging!
We are simply investing our virtual tokens in a mine that is producing more virtual tokens. So, we don't actually own the equipment that produces the tokens, but instead we have decided to invest our tokens into the imprecisely explained promise to receive a certain percentage of tokens generated and calculated from how many tokens we invested out of the total number invested by the whole group. There is no money involved and the tokens only exist by virtue of the fact that a corresponding transaction is recorded on a block chain that has no physical existence. Some people traded real money to obtain tokens to invest but they did not pay anything real (but only tokens) to 'buy into' the promise. So, how can trading in tokens be any different than using Monopoly money to buy four green houses? This is all only a game. It makes no difference if later we can exchange these tokens for real money. There are other games on the internet where we can pay real money to play a virtual game in a virtual world.
The fact that we have this hope and belief that we might be able to exchange these tokens to real cash does not change the fact that this is only a game we are playing.
