Every major crypto developer (Charlie Lee, Maxwell etc) are dumping their projects and are now working on the BTC blockchain. There is a reason behind this.
Let's count the reasons:
-1. Lightning Network.
It is soon going to be mass adopted. There are already some nodes running on the LN network.
Now there are a lot of people that are saying "So what, there are tons of altcoins that already can send transactions with low fees?", but the idea is to prepare for the "incoming" future. Once all exchanges upgrade their wallets to the Core version, the world will be ready for the second phase.

-2. Atomic Swaps.
Imagine a business that accepts only BTC, but you happen to have only LTC in your wallet. You will be able to swap your LTC balance for a BTC balance on a mutually agreed price, directly (Decentralised shapeshift).
-3. Confidential Transactions.
This has already been possible since late 2016, but the community has not yet agreed on making a soft fork that will implement the confidential transaction on the Bitcoin chain. However, it needs to be mentioned, that if such thing becomes possible, forget about all "dark" currencies out there.
-4. Smart Contracts.
The BTC blockchain is designed in such way that it will soon be possible to build smart contracts on top of it. There is no doubt in that.
This is the biggest step that is going to dominate (Like it has not yet xD) the crypto world. Forget about everything else, literally.
This is the reason behind the crazy BTC price and even the huge volatility that it has. There is a huge market, and giving the fact the market capital of cryptocurrencies is almost 500 billion (16-02-2018) -that's literally nothing compared to stock market.
Forget rumors about BTC crashing, banning etc. The futue is here, and its inevitable.
