No altcoin can be better than BTC, and so is NANO. NANO can have faster transaction speeds than BTC, and the cost is cheaper than BTC. But those things cannot help NANO better than BTC. BTC is always the best and only cryptocurrency in this market
I'm also a big supporter of Nano I have seen Nano goIng from 100 sats each to $15 each in the market, Checking their stat we can see also has a huge percentage of profitability,
Bitcoin ROI 8,305.48%
Nano ROI > 9000%
But when it comes to adoption and volume it's still Bitcoin, Bitcoin now has over 70% dominance over altcoins, Nano will have its time but we should all rally for Bitcoin now.
Right now I'm accumulating Banano, who knows there could be a repeat of Nano in the future, Banano is a fork of Nano, since they have the same features, there's a possibility of a repeat, it is now trading at 1 cent to 1 BANANO.
