As long as there is still a lot of positive news emerging and also before the Bitcoin price experiences a deep correction, there is no need to worry about the bull run going to be over. I am still optimistic that the bull run will continue, so I have no plans to sell my Bitcoin at the moment.
Indeed I cannot know the future, because I am not a fortune teller. But I can predict from Bitcoin price movements in the market and also from the many articles I have read. And I haven't found anything that will end the bull run, so I conclude that the bull run will not end any time soon.
When bitcoin goes up, altcoin prices go up in usdt, but they usually either move slightly higher or stay same or even drop in bitcoin pair and that means there is one more step for them to go higher, and that is what we are seeing right now, because bitcoin stays around the same price but alts go up in bitcoin price and that is what I think would be the real alt season and we are at the start of that, I think things could double from here before we can say alt season is over and time for bitcoin to take over again and go up.
The real game changer will be when institutional contribution happens to altcoins, there is really a low amount towards ethereum but that's about it, and that is why I can't really stress enough how important it will be when the real change comes when those companies start to invest their big amount of money into altcoins.
