But now, Bitcoin seems to have become "outdated" and the following altcoin threatens the dominance of the Bitcoin market in the future. Here I am talking about Nano (XRB).
What do you think about XRB?
Rank 38 on coinmarketcap and intend to replace the dominant position of bitcoin. Hm, it seems far away. I think you should look for other options. Maybe bitcoin will be outdated but not in the next few decades.
