This hardwork called SegWit2x will create another branch of the original Bitcoin block chain. Its rationale is similar to what we had in August. The block size is increased to 2 MB (in the original chain of 1 MB). It is expected that this will increase the speed and reduce the cost of transactions in the new network, with the result that the currency will be able to successfully compete with other payment systems such as Visa and MasterCard.
According to analysts, hardwork will be another important event, which will increase the volatility of the Bitcoin's price. As in August, a lot will depend on the support that will be received by each of parts. The fact is that than more support than more transactions, than better growing currency.
