They can only succeed if they did it 6-7 years ago.
Bitcoin has been subject to fud and whatnot since its very first exchange listing, and till this day nothing has changed in that regard. Same fud, same panic, same drama, but afterwards we're breaking through newer all time highs like it's nothing. I have been in Bitcoin long enough to experience the ups and downs, and to conclude that it's not working, and never will work. We just have to accept that due to how unregulated Bitcoin's nature is, which applies to basically every crypto currency, there will be entities looking to shake up the market for their personal gains. Either just make use of the provided market opportunities if you're a trader willing to take an extra bit of risk, or keep holding. Very simple options, but yet people keep panicking.
People keep panicking because they are new people, those that have been hit with crashes before and were able to keep holding and understand what it is going on know this and will never let themselves being manipulated for someone else gain but for the new people in bitcoin this is a new experience they need to go through and until they experience a crash and survive it then they cannot call themselves true holders.
