I was happy ot see the exponential growth the last two weeks at the 3 day chart. but now we have lost almost all the growth. What happened?

I think that it's just a bear trap. Some people may be getting out of the market early right now, but I think that they're dumb to do that unless they're returning very soon after holding bitcoin.
As the halving is still around a month away, we'll see more pumps in my opinion. Larger ones as well.
