Advantage.. Seems like it did.
It did not.
Since August this year 2017, BCH, BTG(wonder when it will be in my hot wallet tho) has been created from fork. Many of crypto investors were expecting that BTC price will declined due to chain split, but look at now,
I wouldn't call those two anything other than standard coins; definitely not a chain split given their minuscule support. The case with the latter, BTG, is much worse as that is an outright scam. Unfortunately, regulators are slow to catch up to all of these and prosecute people who are doing it.
BTC is breaking ATH repeatedly and other forks are following! (B2X, Bitcoin Silver, etc)
The ATH thing has nothing to do with the forks, and BTC would be much higher without them. B2X is an attack, and Bitcoin Silver has literally nothing to do with Bitcoin, same as BTG.
