There's a lot of hate between different Coins in the Crypto market. There is enough FUD without other currencies creating any between themselves.
One that jumps to mind is BTC/BCH.
I think that the whole market needs to pull together to disprove a lot of the nonsense that is posted about the market.
What are peoples thoughts. Is Coin to Coin rivalries killing crypto?
It's a good point that you raise, such rivalries definitely don't help out in many ways. Spreading FUD about a rival in the hope of stealing their custom only works if the custom actually comes to you. In crypto's case it tends to just flow out of the market. There's no use for them to crash bitcoin because it's only going to crash the whole market of which bitcoin cash is part of.
