I don't think op words now hold true. As hard it is to. Believe that last year it was only Bitcoins and now there are so. Many alt coins that have taken over and it's really passing of that these coins are gaining because of that stupid Bitcoin unlimited. ETHERUM and Monore has gained a lot and is posting some serious problems for Bitcoins. If the hard folk does take place it will be a end to Bitcoin and all this alt coins shall rise and rise. I yet don't own this alt coins, but many have made good profits in it already.
If you look at the price, adoption rate, demand and supply. In all these aspects bitcoin will be top always when compare with the other altcoins. I agree that Eth seems increasing in value day by day but still bitcoin is top. I do not know why you think about forking first. Satoshi speculates that bitcoin will reach 10000$ for 1 bitcoin.
Why you been supporting altcoins and degrade the bitcoin's potential. See the price we are always top.
There is no altcoin that have an potential to replace bitcoins in future even if its price keep on going higher and higher as bitcoin is the king of digital currency and even if any altcoin goes higher it can never be that powerful that it can replace bitcoin in near future.
