Its basically pyramid scheme. People, who call it share holding dont know what they are talking about - which is worrying since vast majority of alts, that emerged over the years were shitcoins and get rich quick schemes to begin with.

You offer ICOs to intial backers and insighters, they hold for several weeks following the launch, allowing the price of shitcoin to skyrocket in short term. The founder and insighters then sell their shares crashing the shitcoin and leaving now worthless casino tokens to played fools and bag holders.

Its been done for nearly decade now and will be done again in future, people never seem to learn.
