Nothing is too big to fail in crypto world, Terra Luna is a big example that the safety of your money isn't guaranteed even if you invest in top altcoins out there, it's the same risk involve with crypto generally including BTC
whether only I have a feeling that Terra Luna holders experience that all crypto revolves around that currency?
After the big Luna fall, I have seen many announcements of the crypto world apocalypse. It could be concluded that Bitcoin is imaginary in relation to the super currency Luna.
Trusting the wrong altcoin is a personal mistake and other cryptos, especially not Bitcoin, should not be generalized.
