Well, I say... let them burn their money, if they are doing this to sabotage Bitcoin. Let the miners do their thing and let the developers analyze this threat and implement their counter measures.
We should never forget that Bitcoin is still experimental ... we still need to figure out if the tx fees will be enough to reward the miners.. once the Block reward falls away.
It is just part of the evolution of this technology and ALL other tokens would have collapsed under an attack like this.... Bitcoin is still standing.

No matter what they have done in the past, it's still futile and nothing they do to stop bitcoins from spreading has been fruitful to them, it only ended up in regret because instead of putting bitcoins in the people's blocklists, they became curious about it and ended up becoming investors like just like one of us. Let's just say, that whatever they think does not really define what the reality is, instead, they are just using every opportunity to confuse people and not all of them are fools because whenever they throw these kinds of FUDS people often look for real answers and end up here in this community getting enough answer they really wanted. We have improved a lot in the last 10 years and there will be many more improvements in the future, this is how should one of us think because we are one when it comes to this innovative financial revolution.
