Bitcoin team is preparing to update the bitcoin technology to match the increasing demand for the coin. the slow transaction of the bitcoin presents the main problem.
To solve this problem there shall be an update in the bitcoin code only (soft fork), or changing the whole block chain with better high technology that let the transaction be instant (hard fork).
A big debate about using hard or soft fork is existing between bitcoin team members.
The fear occurs when using the hard fork and not all parties agree for this hard fork, then we will find two types of bitcoin, the classic bitcoin with the soft fork and another bitcoin with hard fork.
This lead to dramatic change in bitcoin price. The soft fork bitcoin with a lower value and the hard fork bitcoin with much higher price. (the same happened as for ethereum classic and ethereum)
If bitcoin developping does not come up soon, bitcoin would lose its value among other rival cryptocurrencies, In other words, bitcoin is forced for this update.
