I haven't thought about that yet, but if many believe that ethereum or EOS, the next bitcoin will certainly take longer or years if they want to replace bitcoin. try to see, the price comparison is still far away, so for now don't ever compare it with bitcoin. without bitcoin, altcoin is nothing.
Yes, I strongly agree, Bitcoin is currently like a very expensive gem, no other Altcoin can defeat the dominance of Bitcoin, it takes a very long time to beat that Bitcoin. Because BItcoin has been accepted by everyone in this world.
