where do you coming from? those who thinking that anyone can replace bitcoin. plus saying specifical timeframes.
These guys probably are writing from a parallel reality where Cardano's CEO is Satoshi. No chance to beat BTC in the next 3-5 years.
BTC might lead the way and who knows in next 10 years what will happen and how it will turn around but essentially doubtful if Cardano could take that long stride in order to beat btc in coming years as it has a long way to reach their.
