Perhaps 20 years in the future if Bitcoin is still the market king and BTC is valued at $100,000.
I don't think so. BTC price is going up and BCC price is going down, who wants airdrop coin anyway?
One thing going against Bitcoin though is it's limitations on being an early generation crypto.
Why do you see this as limitation?
There is always a chance that some altcoin with better tech will pass it up.
Every time potential coin pop out to "take the lead" bitcoin ends up stronger then before.
