So, it's a nutshell ;p
Exactly and if it weren't for altcoins, BTC would still be uncirculated and all in the hands of just a few people.
You could also argue though if not for the shitcoins good coins like XC, Vertcoin, Monero, Minerals etc. would be worth more too. The alt market as it stands isn't creating new wealth, just recycling existing money around from trader to trader, and it is dying fast. Coin pumps used to last as long as weeks in some cases 6 months ago, now they are blip coins that come and go in just 2-3 days. Eventually the masses are going to get tired of it and leave in droves and they already are starting to, it doesn't leave a positive impression of crypto as a whole.
There will be rules for sure. Who'll be able to make a coin, who'll be able to trade coins, etc.
Holding is the key. When people recognize the real value of a coin they will buy and hold, because they believe in it.
For my bad luck, I'm a day-trader.
