What happens is that even if good analyses can be found about the market and about what it could do during the short term this is similar to what we see with the weather forecast, when you see the forecast it is announced the day will be sunny, but then if something happens all of the sudden the forecast needs to change as well, so while decent predictions can be found they are at the end speculation based on the data that is known at the time, which is bound to change depending on what the market does after the prediction is made, which is why anyone which declares they know what will exactly happen in the market beforehand is simply lying or exaggerating the accuracy of their system and the predictions it can produce.
They need to do that because that is the only way to retain their service and people won't use them anymore if they provide wrong predictions. People still use them and don't complain anymore because they already know that it's impossible to predict anything accurately but it's easy to predict shorter term outcomes than the longer term because the gaps are quite close enough or in other words they predict more realistically.
For the price of btc, it finally became stable over 40k and I have a sense that it will now go upwards more than downwards. Buying is fine this way but if you will stick on buy low sell high principles, you can wait for a more bigger dip.
I have seen them price over $44k for a brief moment, it's been a long time since we touch this price, so it's very interesting what will be the movement since we topple it already (although it goes down again to $43,900).
I agree with the buy low, sell high principle, this is the most widely used trading strategy for any market. The only problem is that it's hard to time bitcoin, we don't know if we have reach the floor price. So it's better to just do dollar cost average specially if you are just an average investor or just side aside money month for investment.
