It depends on there offered service and other needs but I don't think with this time no crypto will be able to compete bitcoins. But just like what happened from the early days of bitcoin. We don't know that this will come out of nowhere, then I think some another currency will be able to come out from nowhere and will make some hard competition with bitcoin.
Actually i like bitcoin has more competitor as the biggest price and highest marketcap because bitcoin can do better.
The team developer will try something more useful to bitcoin itself to gain the first stage again example fast transaction.
