Bitcoin cash is a hard diffusion of the original bitcoin algorithm, taking advantage of the fact that it is opend surce to introduce some improvements, which have been criticized and has created some controversies, despite this, many projects have integrated this cryptocurrency and its value in the market has increased considerably. With this hard diffusion of bitcoin, some improvements have been introduced such as an increase in its scalability, greater capacity to handle a large number of transactions as well as lower commissions. In my opinion, many people do not understand what are the differences between bitcoin cash and bitcoin causing confusion.
