It becomes apparent speculation to suggest bitcoin or "crypto" will hit zero, as much as suggesting it will be $55,000 this year. We are seeing the birth of a technological revolution and speculation is all we have, for certainty is a fools game. Coins like Dash, Monero, Zcash, Ethereum, Bitcoin and many more are all real use case coins with well respected development teams.
It is also foolish to believe Bitcoin as the one true currency, competition is healthy in the crypto space and breeds future innovation, we need multiple platforms for choice on the open market. If we happened to be a single currency world, then it would be worthless as a commodity. So one possible way for crypto to hit zero, would be for everyone to just adopt Bitcoin.
now may be time to spread those assets to help catapult crypto as a mainstay.
We cannot deny that the crypto space is truly driven by speculation these days. Anything could happen in the future whenever prices go all the way to the moon or all the other way around. For crypto to reach $0 in price, something terrible needs to happen that will lead towards the closure of the crypto market and the decline of usage from people in the mainstream world. As long as Bitcoin lives, there's hope that the Blockchain industry will keep moving forward. The naysayers (like Warren Buffet) will always say that crypto will go to zero because they don't understand how it truly works. Crypto is both a technological and financial revolution that gives people power over their own money. The fact that there's no central authority behind it, makes crypto a truly indispensable tool for mainstream payments.
Nonetheless, there are so many good coins out there (like Bitcoin, Ethereum, and DASH) which have provided real use cases to everyday people. As long as there are developers working hard on these cryptocurrencies (and people use them for mainstream payments), they won't be going anywhere. For now, prices will continue to rise to "infinity and beyond". In the worse case scenario, prices could go all the way down the drain in a blink of an eye. But the crypto market will not go to zero as long as there are people buying cryptocurrencies worldwide. It'll be here to stay for a very long time. Just my thoughts
