Most members keep on asking each day that the crypto activities we all know of and have been hyping will collapse. Some expert investors who don't like Bitcoin, Crypto and blockchain tevhnology always say the bubble will burst and everything will come to zero.
It feels like you are not very sure and secure about the future prospects of crypto yourself, so you come up with all these questions to receive a bit of positive feedback that will help you in fighting with your doubts, your "inner demons", right?
Nevertheless, let me play the devil's advocate here:
* A market capitalization of about $252,730,956,280 (CMC now) going to go a waste?
This cap is all fake and bogus, these are not real dollars that can be lost and thus can't be lost, which seems to be your logic behind this question. So yes, it can all go to waste overnight if things go massively awry. Well, maybe, not overnight literally but faster than you would hope for (if things start falling like dominoes).
* Big companies such as Binance, Kucoin, Huobi, Bithumb and the rest going away?
Even bigger companies from the real as well as financial sectors went bust pretty fast. Lehman Brothers, LTCM, Enron, Kodak, Pan Am, and a lot of others. Also, the companies you mentioned seem to be all exchanges, so it may take just one successful hack to shut them down for good in an instant.
* USA and other countries boycottimg their regulations and China forgetting about their intention to set up new regulations on crypto?
Don't know about China, but in the US you won't get away with crypto if you don't pay all respective taxes. Actually, you can, for some time at least, but if you get caught, you are on your own, and good luck to you claiming that as your line of defense in court.
* Awesome blockchain technology that many governments are interested in going a waste?
This doesn't have anything to do with crypto, and I'm highly dubious whether that many governments are actually that much interested in the blockchain technology in the first place. Anyway, if the whole cryptoworld goes to hell one day, it won't in the least affect whatever those governments are doing with the technology or using it for.
* Huge investments in crypto turning to zero
* And even Satoshi Nakamoto not doing anythimg to ensure what he pioneered sustains and endures?
These are no guarantees of any kind. People invested in many things and still ended up losing all in the end. If anything, huge investments have already been lost when bitcoin crashed 3 times. Did they prevent bitcoin from crashing? And I don't really know what Satoshi Nakamoto can do about that. Maybe, give back your lost money, huh?
