Now, in principle, it is largely decided what will be the future bitkoyna. On the one hand, he is now hopelessly outdated, slow, his transactions are hanging by hundreds of thousands, commission fees for transactions are prohibitively large compared to other crypto-currencies, and this caused justified criticism of him and the transition of some users to bitkoyn cash. On the other hand, the network of lightning has successfully passed the test, which should be soon implemented on bitcoin and which should solve almost all the problems that exist in the original bitcoin. If the advertised improvements in the network of lightnings work, then the initial bitokoyn expects a good future.
Yeah. If Bitcoin takes long to implement scaling solutions like The Lightning Network, then other altcoins will continue to rise in value and take the pioneer cryptocurrency's dominance in the market. Right now, Bitcoin Cash has taken a huge advantage against the original Bitcoin by successfully implementing a block size increase to 8mb. While the downside to this is that it further centralizes the cryptocurrency, it provides many benefits such as cheaper fees and high transaction throughput.
On the other hand, Bitcoin is having a hard time to get accepted as a cryptocurrency for mainstream payments due to its increasing fees on the network. Thus, the longer Bitcoin takes to resolve this issue, the lower the possibility will be towards becoming used as digital money all around the world.
Nevertheless, the future of Bitcoin will be determined whenever it could be used as electronic peer to peer cash or just as a store of value. If Bitcoin fails to provide peace of mind, then its future will be doomed. Just my opinion.
