Sorry OP Bitcoin almost complete it's ATH this cycle, I can't forgive myself if I ever advice a newbie to start investing right now, the Bitcoin cycle is almost over, I advice you should wait it out, wait for the next correction in 2026.
This is the best advice I can give any newbies, it's possible that the next low in a year time will be $40,000 and this will be the perfect time to start accumulating once again...
It's very difficult to make recommendations, but I think everyone sees a significant difference between the current bitcoin cycle and the previous ones. Institutional investors entered the market, ETF appeared, mass acceptance of BTC as a strategic reserve asset, and much more.
You are very mistaken to say everyone, because to me it looks like most people are in denial especially in altcoins. They refuse to believe that it could be a different cycle, but everything makes it look like that it is.
Right now it is hard to say that Bitcoin has already reached its all time high in this cycle. I think it will happen at the end of autumn or maybe closer to the end of the year so there is still some time for Bitcoin to grow. But counting on big profits now is definitely not worth it because the bull run is already in progress. However if a person has entered the cryptocurrency market and wants to buy something the only thing worth buying now is Bitcoin everything else looks too complicated, and I would not recommend buying altcoins in any case.
The truth is that nobody really knows if this will happen or not. Everyone is guessing based on many metrics, but it looks like this cycle is quite different. Still I would say that selling at any point in this cycle is a mistake. Why settle for small profit? Either go all the way or go down fighting.
