It's completely normal. People need time to get accustomed with the prices. Do you think $1000 for a BTC is a lot? Would you pay it now or say it's too much? For many years $1000 was that mental barrier and people were dreaming of cashing out at $1000 and saying that nobody would buy above that price.
Just wait and if the price doesn't fall below $3000 until the end of the year people will start treating it like something normal and consider everything below it as a low price.
they want to wait for the time when bitcoin will drop huge value.. so that they can buy plenty but they dont realize that bitcoin is keep increasing to the point that every month it increase by 1000$ value. and now as of the moment bitcoin is 6100$ .. i dont think bitcoin will drop down to 4000$ level. end of the year we will see bitcoin in the 9000$ level. so hodl your bitcoin and altcoins .. altcoins will increase 20 folds aswell

soon plenty people realize that its too late to invest to bitcoin because its too damn expensive. they will regret not investing early in bitcoin. they closed there mindset because plenty people saying that bitcoin is a fraud. people saying that bitcoin is a fraud is dont know how to accept change.
That's why they are really afraid to get it, they keep on waiting and it the value didn't drop to their desire, they won't be buying it. Then its become more of a mental barrier for them now to get bitcoin and they haven't notice until some time that the price of bitcoin is going higher and higher to the point that they cannot afford it anymore, thus the fear is getting stronger.
Well you will just have to convince yourself that Bitcoin will rise in the long-term. Look at graphs of Bitcoins price rise. Observe even if you want for ours that long-term positive bullish trend that is a defining characteristic of Bitcoin. Imprint it in your mind and you will want Bitcoin immediately. Also another method would be to look at the major price falls and then compare it will the major price gains. The price gains are always higher. And see how Bitcoin rose to never before seen heights even after a major fall. This will hopefully stop you from doubting the potential of Bitcoin. I personally do not doubt the potential of Bitcoin and I hope you train yourself not to either.
Bitcoin is for long term hold IMHO, if you look it at short term not only you will not get a huge margin of profit but you will not have the guts to buy it whatever the price will be. Your mind has been somewhat imprinted that bitcoin will not get the profits you want short term and might as well go to other source like altcoins.
