prices are falling. Keep calm and watch the news. If you are not calm. You will lose a lot of your money. It is best to wait for the price up and you will be profitable. I do not know how long it will take, but I still believe in it. will increase the price
I agree with you, uncertainty regarding the future outcomes is the biggest reason for not holding the coins, The most losses of investors of gains is investing on scams coins or selling too early on promising projects, Then boom, out of a sudden news leak on reddit and the price hikes basically overnight. Since you cannot time these it can be a good strategy to simply say "find a coin you believe in and just hold it for at least several months - it may not go up immediately, but in the long run you will be happy".
you should not be worried when price are falling if the prices are falling so it will not be a permanent fall it will be a temperory fall of prises therefore you should not be worried of loosing money it will be an opportunity to buy more and more bitcoins because it will not be a permanetn fall of bitcoins.
