After bringing millions of users to the cryptographic space, Bitcoin has found a log jam in its network, since the available blocks are filled with transactions faster than they can be mined. This delay has led to higher transaction fees and longer waiting times.
Where is Bitcoin going?
Currently there are plans in progress for the oldest and best known digital currency to try to overcome this problem of scale. Some of the solutions considered include the Network of Lightnings, or important updates to the network such as changing the size of the blocks.
Very difficult to overcome
Bitcoin is well entrenched in the cryptocurrency space, and will probably be a leading currency for a good while while people refer to Bitcoin before anything else. But, as the community matures, explores and demands more, Bitcoin could be in trouble. Changes need to happen, and although Bitcoin will not fall on its sword too soon, if it does not make changes, then the potential for failure will continue to increase.
