I'm still new to cryptocurrency, so forgive me if this is a gumby thing to ask, but is forking positive or negative for the currency as a whole? From what I've heard cryptos like NEO have come along as 'superior' because forking is less likely to occur. It is hard for me to tell at the moment what is hype, what is speculation, and what is genuinely true with regards to what will keep cryptos sustainable, so any clarification would be greatly appreciated.
