There should be a way to vote down content that is so misleading and irresponsible.
Nothing is guaranteed. Not even that Bitcoin still exists in 2021, or even next year. It could be wipe out by a better technology or by a security disaster in no time, at any time. Improbable in the short time? Maybe, but definitely possible, therefore absolutely a million dollars value is NOT GUARANTEED.
This is just a hype creation for circlejerking and getting more people buying. And since he and others like him are heavily invested in bitcoin their posts can be almost considered bait for a scam.
It is unethical to make a claim like these ones from OP.
