Bitcoin is not yet pumped. It is still at a very low level in my opinion and gives a buying opportunity. I think you've heard of the halving and wondered what caused the recent spike. The reason is the approach of the halving and the expectation of a bull run. For a long time bitcoin has been in a stagnant state. So it hangs around 25-30k. In some periods, its value fell a lot, but it quickly recovered. Since the expectation of those who follow Bitcoin is that there will be a bull run in the next 1-2 years, the things mentioned may seem like bitcoin is pumping to you. We haven't seen anything yet. Bitcoin will have much better times.
Pump and dump always happened, but it may be not a very significant change. If you means bullrun season, sure it doesn't happen yet. You must know that the bullrun season is predicted to happen in 2024-2025. The significant change in Bitcoin price will come after Bitcoin halving happens, it won't happen in this year.
Bitcoin price already passed $30k, it even reached $31k a few days ago. And it looks like to survive above $30k, there is a possibility for a new resistance. So, you shouldn't mention $25k anymore, it was the price in several weeks ago. I believe Bitcoin price will stay above $29k-$30k if there is no much bad news again.
