Understand the scale of exo vs. terra, etc. The most powerful ASIC cards right now can perform 18 Terrahash/s. This means there are at least 8 million ASIC cards out. Bitcoin has been dealing with skeptics and naysayers for more than a decade. One strategy is the so-called 51% attack, where a malicious entity gains control over the majority of a network's hash rate and effectively takes over the system. 51% attacks are one of the most legitimate threats to BTC.

A 51% attack is an attack on a blockchain by a collection of miners in charge of >50% of the network's computing power. Normally, blockchain operations should be impossible to disrupt because it is not easy to get a greater than half of its community to kick against an existing rule. However, certain blockchains in the cryptocurrency space have suffered this disruption Bank for International Settlements (BIS) general manager Agustin Carstens has criticized bitcoin saying the asset was inherently risky and increasingly vulnerable to a 51% attack The 51% attack has been a theoretical bogeyman in Bitcoin for much of its history.

Therefore, 51% attacks are highly unlikely to happen on big networks, especially on the Bitcoin blockchain, which is considered the most secure cryptocurrency network. While many of the large blockchains have not yet suffered an attack of this kind, the majority attacks have been seen on other smaller chains In other words, Bitcoin Cash and Bitcoin SV have a hash rate of 2-3% of the Bitcoin hash rate. Someone who wants to destroy Bitcoin Cash and Bitcoin SV would simply need to perform a 51% attack. Essentially, if someone controls more than 50% of a cryptocurrency's hash rate, then they can rewrite the blockchain in order to double-send.
