When you think of coding money, you often think of Bitcoin. But now, Bitcoin seems to have become "outdated" and the following altcoin threaten Bitcoin's market dominance in the future. Here I am talking about the Nano(XRB). Nano can handle 7,000 transactions per second and this rate can increase over time and can even compete with Visa. The secret behind this is the block network architecture, which allows transactions to be processed extremely rapidly. This transaction speed allowed the Nano to become a potential co-dominant market for Bitcoin's pre-encoding market.
What do you think about XRB?
These coins are very much and it will take a lot of time to describe the advantages of each. Bitcoin is obsolete in terms of technology, but it will remain at the very top. The second line can be fought by any of the alts if he wants to and he has enough money and power.
