A SPOF In Blockchain Is Centralization And Control
A single point of failure (SPOF) in a blockchain is losing (or not achieving) decentralized status and relinquishing control of decisions to one person, team, or private company.
Having significant influential personalities expressing their thoughts is not failure although still depends on the situation. For BTC what happened was a "leader" appeared out of nowhere, rallied behind him some influential developers and those controlling Bitcoin's websites, while building a sentiment in the Bitcoin community, that he was the creator of Bitcoin, Satoshi Nakamoto.
Far from being Satoshi for many reasons, also having denied it when asked, Adam Back, is the powerful personality that controls every development within Bitcoin today.
Leaders Provide To Their Community
Leaders attract people and rally those around them with their actions. They don't beg a community to make them a leader, but are recognized as leaders with their hard work, dedication, and devotion.
A leader inspires confidence and certainly is not a shady person but transparent and honest with the rest around them. You can't be a leader when your personal interests are above the rest. Needless to say Bitcoin Cash doesn't really need leaders, but there can always be some personalities that have what it takes to promote and send a powerful message.
BCH requires professionals with a honest and serious approach, and already has plenty of them. The more it attracts the better it will manage to cope with the increasing competition.
Leaders of Bitcoin Cash are the developers of Bitcoin Unlimited, Knuth, Bitcoin Verde, smartBCH, Bitcoin.com, General Protocols, and any BCH dev working on blockchain improvements, on sidechains, on infrastructure.
Leaders are top investors of Bitcoin Cash, Roger Ver, Marc De Mesel, Jihan Wu. They don't ask to lead, they just rally others around them with their personalities.
To simply put it, the guy that will talk about leadership too often, is not a leader.
Everyone understands when someone is simply opportunistic in Bitcoin Cash, and accusses developments simply because they will not directly profit them.
SmartBCH is a threat to a few individuals, simply because they hold zero BCH. They sell all BCH they receive for USD, so they wouldn't care for any developments that can become a positive factor for BCH price, if this development doesn't profit them in USD directly.
One person was supported so far by the BCH community to run a campaign, but is full of hatred against smartBCH. Made videos, and posting threads acting like how he thinks a leader should be, with arguments on BCH strategy, while completely ignoring the correct approach but this of course on purpose, since with this guy there is always one.
The same guy that promoted a smartBCH scam bridge a little while ago, against every warning and advice from the BCH community.
Who can take this person serious when all he does is against Bitcoin Cash and SmartBCH.
All this while at the same time you don't even hold any Bitcoin Cash.
Finally
To this person and some that dissapointedly followed them, I tell this:
If you wanted BCH to succeed you would have taken a different route. I don't doubt, I know you hold no BCH and probably never held the Dash you received or no other crypto either. You are a mercenary and speculator, what you love is the dollar, not crypto.
At least be honest and stop manipulating those that follow you, although I doubt you can be honest ever. Turning black into white is your idea of personal improvement. Well, you probably don't get it, but you are mostly ignored or even hated by plenty. A community that had to fight some real battles simply ignored you, but you are not fooling anyone, you got some final funds so some numbers on a map appear more. You didn't do any real work that helped you.
Your associates did everything, and you will stil get most of those BCH and I am sure you sell it all a minute later.
Bitcoin Cash may or may not need leaders, but certainly doesn't need a fool as one. Next time I am mad with someone paid to do a job and fantasizing wealth and power I will refer with names. Staying low for a while is your strategy now, just stay low forever and don't resurface the leader ambitions.
