Should Crypto-Owners Be Worried??

With the high volatily and at some point price instability of cryptocurrencies , us cyrptominers, crypto-owners and crypto investors might be a little bit worried after the recent rumours (probably might be true from what i've been reading and seeing around...well it is true) about plans by the Chinese government to ban crytocoin exchanges including Bitcoin.
We all witnessed what happened after China banned a list of ICOs. Most of the coins/tokens took a deep dive...I went to sleep and in the morning when i woke up it was like some kind of bloodbath had happened in exchanges..Nearly all coins were red...The cryptomarket was in a panick mode.Investors thought they would lose all investments therefore most of us were opting to dump.
Something to smile about was that it wasn't long enough till this coins got back on their feet and we could see a number of greens again.
Now lets go to the Big questions.
What would happen supposing China bans all crytocurrency exchanges?
How hard will it affect the Cryptomarket? Will the crypto ban be strong enough to render cryptocurrency useless?
Do you really think China would throw away this amazing promising currency technology considering they like new great opportunities like these as long as they benefit? Infact they are one of the biggest crypto investors..
Or maybe these are "just threats"...We wouldn't know yet.
Those are just some of the questions to answer and the list is endless.
Personally i think we shouldn't be worried that much. Bitcoin is here to stay and it will stop at nothing.
Feel free to give your thoughts and opinion on this..!
Great crypto-minds can offer a solution or solutions if at all there's any.
