Now about the topic
What will it take for any altcoin to take the throne of bitcoin?
For an altcoin to take over Bitcoin throne, it must have a stronger community than bitcoin which I think it's possible and Bitcoin community is something else.
If you noticed world market in the crypto, all markets to follow bitcoin trend most of the time . If Bitcoin fall most of them will fall on a bitcoin rise most of them will rise.
If altcoin can build a stronger community than bitcoin it will surely take Bitcoin throne
I quite agreed with you, altcoin could be stronger than Bitcoin as time goes on I strongly believe that.
