Taking into consideration the fact that the Bitcoin has the most transaction traffic per day among the cryptocurrencies, servicing a huge amount of transactions will cause congestions to miners in the network and that's still the big problem of Bitcoin as of this time.

The sole purpose of the Segwit2x and Lightning Network proposals is good in lowering the tx's fees but it didn't get through because of the consensus that also didn't met and nothing we can't do about it as of the moment but to trust the Bitcoin developers to find a much more better way for the betterment of Bitcoin itself.
