When bitcoin price falls its when investors do have opportunities to make profit in the market except someone that does not know that drops of bitcoin price is an opportunity that someone can use and get more of profit when it buy and keep for ongoing time and especially when the price of bitcoin goes up, the people that doesn't invest in bitcoin when the price is falling is new people that doesn't know that price of rising is for advantages for investors, bitcoin investment is good to invest when you know the time to invest, sometimes new investors like to invest when the price of is rising and it pushed to buy the time the price is rising but that time is not the best to buy bitcoin

There are so many people who are forgetting that, it's simple and you just need to buy it when it goes down. The simple statement of "buy low, sell high" is still very true and has been true for every market. Of course you need to be careful about what you are buying, I am talking about bitcoin here and not some small low cap token, that could be lower and then keep going lower as well so you shouldn't be really expecting any changes at any time soon.
For a trader to trade with market trends, trading in Bitcoin is more efficient than other lowcap altcoins. A lot of traders make losses by trading in lowcap altcoins which they could have profited from trading in Bitcoin. The market does not always give the opportunity, so it is also important for the trader to use the opportunity properly which I have learned from my trading experience. When the market starts dumping, it is considered a huge opportunity by some traders.
An experienced trader will never risk his capital, that trader knows how to follow money management. So the best time for Bitcoin traders to enter the market is when the market is going down and even experienced traders follow it well.
