Probably you were witnessing the memes about 'I keep buying the dip but it keeps dipping'
here is what's happening:
- no one knows how deep we're going to dip
- no one wants to miss the opportunity
Reactions & approaches are what makes the difference between traders

how & where to buy?

I had problem finding entries when I entered crypto
one thing you can do to find a good entry for yourself is to divide a leg, use fib tool or gann box
First divide it into 4 equal parts, that 0.5 level is equilibrium
Then find the midpoint of both upper and lower half too (0.25 , 0.75)

Now you can apply midpoint of the range from level 0.5 to level 0.75, and also the range from level 0.5 to level 0.25, these will give you some precision around the context we're talking about

Dashed lines are where we can bid
The orange box is very close to infamous 0.61 fib level
that's my OTE: optimal trade entry

You can have 2 different strategy to make bids on the specified dashed lines as levels of entry:
1) make bids of a third of your prepared capital on each of 3 levels
2) make a bid equal as X on the first level (0.5), make another bid equal to 2X on the next level, 3X on the last one (giving more weight to lower prices)
