Anyway,yeah,some altcoins might bring bigger profit margins than Bitcoin,but I don't care that much about altcoins.
The current Bitcoin price pump might be a short term bubble,a long term bullish rally or something in between.
I don't see an obvious factor that helped for pumping the price.It seems that optimism is spreading across the crypto markets.Maybe new people are joining the crypto world,seeking for safe heaven assets.
It is certainly not a bubble because in definition bubble has to be something that goes up super fast super a lot and make a huge craze all around that place where the bubble happens and eventually burst. Now looking at bitcoin in order for it to be bubble first of all we have to increase a lot more, right now it is not really any place where it could create a huge burst that would affect the world, right now if bitcoin becomes zero and all of bitcoin in existence just gets deleted that wouldn't hurt the world.
Of course it would hurt us and all the people who hold those coins but that number is low compared to the general public and the amount of bitcoin is low compared to other financial stuff so the end of discussion here is that it is not big enough to be bubble. But I also think it will not burst, yet that is an opinion and not a fact, I can't know that.
