Bitcoin now is too big for a bubble or the risk is ever the same?
"too big for a bubble"? No, it is different - as it grows bigger faster, the bubble is expanding further which means that the crash will also be bigger
If you think it is a bubble, that is. The price is rising, yes, but what exactly makes yoı think it's a bubble?
Because it fits all the parameters of a bubble as we have seen them again and again. What is needed is that you prove why this for the first time in the history of the world is different. And don't start on the "new technology" speech, because we have been there many times before with technology that was much more disruptive when it came out such as the steam engine, the printing press, the airplane, steam ships, the internet and so on and so on and so on
I choose to look at it not only in terms of bitcoin, but cryptocurrencies as a whole. Some altcoins are rising, some are falling and some are stagnant. Not every currency is rising infinitely without reason, that's why I still don't see where the bubble exactly is. Sure, the bitcoin price may be higher than it should be right now (due to excessive demand, bullish markets, whatever) but the price can eventually correct itself and not necessarily in the form of a bursting bubble, destroying the rest of the market along with it.
