When talking about the possibility that BTC will die, I don't think so, because BTC has become a reference for all coins. if btc die who will be the successor, ETH? No, because ETH is also very close to BTC, the proof is that when BTC goes down ETH goes down and I almost never see ETH go up when BTC goes down, it is a sign that ETH is still closely following the movement of BTC.
