1. Competition in the crypto space can increase FUD among investors
The narrative that people get that cryptocurrency is a get quick rich scheme will play a role in making people be in FUD when it comes to investing in cryptocurrencies. A newbie without the knowledge of the market can be told to come and invest and make millions of naira in crypto, but failing to understand that it doesn’t work that way and you’ve to be patient enough to make that happen can make them lose interest in it if they fail and lose all of their money. This can happen in most altcoins and without knowledge, they can just generalize it on cryptocurrency entirely without knowing they’ve done the wrong investment.
2. Bitcoin's decentralised nature, because I once talked to a friend of mine about a possible investment into Bitcoin but he was like if them run with my money who I go hold?. So stuffs like that can cause FUD in Bitcoin.
Investment in bitcoin has been proven to be worthy of you’re your own keeper. When you trade with centralized exchanges to keep your money, you’re at risk of losing everything but with a decentralized wallet well secured, no one can run away with your money.
3. The government of the country can also make people doubt the potential of Bitcoin, with the implementation of anti-bitcoin policies and regulations.
This is actually true and without a good policy to make the use of bitcoin and cryptocurrencies convenient for the public, they can easily feel not interested and feel pressured not to even give it a try or even fear the punishment enacted on people that trade it.
4. Traditional banks may spread FUD out of fear of loosing out of the market to crypto Bitcoin due to people's continual interest in Bitcoin or other crypto currencies.
This competition cannot be stopped, when you see someone in the same business with you, you’ll try everything possible to make their business not thrive ahead of yours. You can either chose to do it legally by showing to your customers the importance of using your products ahead of other competitors, and do it the illegal way of sharing propaganda against them which is what the banks are up to with bitcoin.
