As such, the larger the Blockchain,

That, or he is a brilliant strategian because any attack which involves throwing
more hashpower into the network is bound to backfire.
Not exact matches
Nor is it relevant in comparisons to other superior coins like Nano (faster, free, and
more scalable than bcash with no miners corrupting things and polluting the environment) which is secure without any network
hashpower.
That's
more than 3X the current
hashpower on the entire network.»
A «51 % attack» could theoretically allow an entity that gained
more than 50 % of bitcoin's total network
hashpower to double - spend bitcoins, reverse transactions and prevent block confirmations.
For example, this was the case with BIP66, when
hashpower indicated they had upgraded when in fact
more than 50 % had not.
«As Bitcoin's value rises, the ability for miners to drive difficulty by adding

more computing is required.»
The good news is that it seems
more computing power is joining the bitcoin mining force and the
hashpower has also grown in the last three months.
Ethereum is still primarily a GPU - mined asset, so any strong crypto without ASIC mining hardware (Bitcoin, Litecoin / Scrypt, Dash) that relies on proof of work is arguably competing for finite Ethereum
hashpower, but ETC represents a much
more direct alternative that so far looks very attractive.
