Bitcoin will not rise straight up to 50k. We will see many up and down before Btc reaching high level. One days ago (30 Apr) Bitcoin price again down to 28k. now its looking weak and we can again see some further correction to 26k and then it will be time for whale to push big than previous and 35k might he target in this pump.
A straight rise to 50k would be kinda impossible given the current market conditions. It's currently undergoing a price correction, and it's probable that it will remain in the range of 25k to 35k for some time, possibly two to three months. However, I believe it could reach another level by the end of this year, possibly around the range of 40k to 50k.
There is not specific reason for btc to pump or dump because btc is totally decentralized and its price depend upon supply and demand law. The higher the demand, more buyer will enter and price will increase. Demand increases with the big adopting news, Btc Halving, Failure of traditional bank and many other. High volatility of Btc is often did not considered good sign for Market because this increase in price is because of News(failure of bank) but we can see sudden drop in price also.
Indeed, anything can happen in the market and news events can also have an impact on the price of Bitcoin. However, the supply and demand dynamics remain the primary factor affecting the price, as you mentioned earlier. I think as the Bitcoin community continues to grow with more people investing and adopting it, the outlook for Bitcoin's future remains positive, so there's no reason to fear for it's future.
In bitcoin we trust:)
