1. Competition in the crypto space can increase FUD among investors
Bitcoin do not have a competitor, and it can never have a competitor, because it is unique and will always remain unique, because it is only people who do not understand this concept that will compare Bitcoin to altcoins, it is totally different in all ramifications (i.e volatility, usefulness and influence on the global economy).
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.
Yes, it's true, but all these kinds of excuses only boils down to lack of proper knowledge about what Bitcoin is, how it works, and best measures to approach it as a new investor, because inasmuch as it is a proven digital currency for over 14yrs, as a new investor, starting with an amount you can always afford to lose is always the best practice, of which with the help of some exchanges like "Remitano", people can now invest with Bitcoin with as little as $2.
