Lately it was found that more than Half of Dash hashrate was controlled by 1 entity, making it possible for that 1 entity to launch a 51% attack and hijack the entire network. With the Bitcoin Cash Hash war fresh in people’s minds and the recent 51% attack on Ethereum classic, this puts another slash against PoW coins and tilts the tables mor ein favor of PoS. Dash is implementing a solution for this called “Chainlocks” and hopefully it can be done without a serious attack being carried out.
