So basically you want to form a contract, arrangement or understanding with the top holders of blackcoin for the purpose of fixing, controlling or maintaining price in the market? Do you realize that this is EXACTLY why Crypto exists in the first place? To avoid central authorities that hold all the power. Collective refusals to supply (top holders deciding to remove their sell orders) to create artificial price rises didn't work too well for Mint now did it. Be aware that what you are suggesting is the forming of a cartel, a collection of would be competitors who form contracts, arrangements or understandings to significantly lessen competition in the market. This is illegal in nearly every civilized nation state in the world - and for bloody good reason. It rips of consumers. People must pay a grossly inflated price, far higher than would otherwise be the case had it not been for the cartel. They therefore just don't buy - the coin becomes a rip off, a scamcoin. The only winners are those who hold massive stacks of coins - those that would have ordinarily bought in would see or hear about this and promptly give us the middle finger. Certain individuals have alot to gain from such an idea but the community loses out. Not to mention it only takes one holder to leave the cartel to cause a collapse.

The only legitimate way to increase the price is to buy up the sells on offer and keep buying them up. If that doesn't work and the price still drops then sorry, the coin just ain't worth what we would like it to be - yet. If someone wants to pay $2,000,000 USD and push the price up to 13,000 Sat then go for it - but don't think you can just collectively stop selling or fiddle the market and suddenly people will pay twice the price. People will pay twice the price - If the market cap doubles.

What does that have to do with blackcoins vulnerabilities? You are just trying to change the subject instead of analyzing blackcoins security flaws.
