However, I think they are speaking to traders. If you are looking for short-term profits, it doesnt make sense to buy now if you think it is going to go down.
Traders generally don't really mind the direction of a market, they just need the price to be volatile. If you think the price will go down, then open a short position, if you think it will go up, open a long position. If the price swings aren't severe enough for you, then you can choose to leverage your trades. In other words, there are plenty of opportunities to trade current market.
Funny thing about waiting for clear bull trends is that it is different for each person, which also depends on how well you understand this specific market. People should only care about when they are comfortable buying in, not about what others think is the right moment to enter. Most average coiners wait for the price to have gone up considerably before they even consider buying, which explains why so many of them have been trapped last year.
