With in the crypto market, some other altcoin will come very very strong and will challenge BTC and even it may so happen that it could surpass BTC in terms of its valuation.
BTC is always over congested in terms of transaction and block confirmation and it is fast and this is the major issue with BTC and people are even opting for second channel to transfer their cryptos from exchange to exchange or to their wallet.
Like if someone wants to buy BTC from an exchange and want to tranger it to another, then he is buying some other altcoin which is fast in transaction and fees and then transferring it to the desired location and gain doing the conversion to get BTC back.
This is what most of people including me are doing owing to much more waiting time in transaction and also high fees of BTC
So we may see other altcoin like ETH or EOS which are quite capable to take the place of BTC.
Thank you @cryptographic and Have a great day.
