All projects get FUD

Troll:

"a mythical, cave-dwelling being depicted in folklore as either a giant or a dwarf, typically having a very ugly appearance." Not These

In crypto we actually mean internet trolls, " In Internet slang, a troll is a person who sows discord on the Internet by starting arguments or upsetting people, by posting inflammatory, extraneous, or off-topic... "

Crypto trolls are an advanced breed of the internet trolls and much worse, because they have financial motives to do the trolling.

Nowadays Crypto trolls claim to possess superior research capabilities, higher intelligence, powerful tools, God like knowledge, and powers to forecast the future. These superior beings hardly need any sleep or rest, and will go on the attack day and night. They can't be proven wrong, because they have a track record of trolling anything and everything, so when a project fails they add a plus to their credits, and when a project succeeds, well they are not wrong, it will take a little more time for them to claim a credit, and in the world of crypto, every project is bound to see some downturn, during which the troll can claim victory.
