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 But now, Bitcoin seems to have become "outdated" and the following altcoin threaten Bitcoin's market dominance in the future.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?
There are many altcoins that can handle thousands of transaction per second but they are nowhere to be seen near BTC. Even nano price today stands at 7 USD. I can't predict future but it's not valid to say today that BTC is outdated and has threats from various altcoins. Being the first cryptocurrency, BTC still dominates and control the crypto market.
