There's currently one big player capable of more than 50% attack on the network (now 90%). Please check it out here: https://cash.coin.dance/blocks/today
My friend just told me that he was able to double spend bitcoin cash using ABC wallet. That's huge, got few coins for free. :)
Anyone else maybe?
How could he double spend? sending a transaction with the same input right after or with a 51% attack? As for as I know bitcoin cash removed the Replace by fee feature.
