Safety is paramount for all blockchain platforms, according to Satoshi Nakamoto, in Bitcoin’s white paper,

“The system is safe as long as honest nodes collectively control more processing power than any group of cooperating attackers.”

Bitcoin, having the highest processing power, increases the improbability of external or internal attacks, is emerging as the “safest Blockchain ecosystem”.

The only way to control this system in a malicious way would be for the attackers to control
the majority of the processing power on the blockchain. Recently, Bitcoin Gold, Verge
and ZenCash, were attacked by malicious miners, taking control of their networks and
forcing other miners to double the cost by imposing a blockchain that has been mined to
propagate, and created a bifurcation that invalidates previous transactions.

Bitcoin, the original and longest running blockchain, has not been attacked in any way,
despite being exposed to attacks on many different occasions. An attack on Bitcoin is literally impossible since it will take about $2.3 billion in electricity and mining equipment for an attack to have anny success. Bitcoin appears to be the safest blockchain against internal or external attacks and will remain in charge of protecting history and its legitimacy as a technology.
