Fear is too ways. It can make you be nervous on where you put your money and proper step of losing your investment but to see it growing. At the same time fear can make you not take the bold step of investing aggressively into bitcoin when you have the money. However, a new investor that don't have confidence in bitcoin, can start by investing with little amount buying every week or month consistently and persistently.
In the second year when he has start to understand bitcoin investment, he can increase his DCA amount due to confidence that he has gotten in the market, because I believe that you confidence i bitcoin will increase based on the passage of time. This is why any investor that has invested in bitcoin for one complete circle will have more confidence to invest aggressively in bitcoin than a new investor. The more experience that you have in the market, the stronger your confidence in bitcoin's future and the less your fear to buy more and hodli for long.
One more thing I like to add is that during our course of investment we see distractions like we have these days in the form of 'Trump Coin'. Such distractions are tempting but they are short lived and are useless in the long run. For investment, Bitcoin will be our sole target for accumulation and one must not deviate from it.
No reasonable Bitcoin investor or someone that truly believe in Bitcoin will be distracted by this trump coin that was newly launched, it is obviously a rug pull game waiting to happen, and it's going to manifest in no distance time, it is just a matter of time, because with all the hype's surrounding it, president trump wouldn't even step down before the coin will start crashing down, so it would be very stupid for any Bitcoineer to even consider investing in it, with all the knowledge he or she has attained in this forum.
So in my opinion, the best way to overcome such distractions is not even entertaining such news on the progress trump's coin or any other coin has grown so far, because it's just a disaster waiting to happen, if you falls for the hype.
