Other altcoins and app tokens will gain popularity. However, the bitcoin blockchain is the most important one and will not be replaced.
yep bitcoin can't replaced the popularity and price far ahead from another altcoin but in the future no one will ever know what happened there will probably be another altcoin can defeat bitcoin
I agree, anything is possible in this rapidly developing world in terms of technology. Bitcoin can really be replaced by another crytocurrency if one created such crypto that its feature are better than bitcoin. We will just know people stop using bitcoin and start using that new crypto.
