Lol, I didn't say that would be the end of Crypto though. Here's my actual prediction;
Right now we see a big drop since some countries have banned or threatened to ban, the drop is directly linked to the number of people selling off their Crypto, other markets (exchanges in other countries) get flooded, more supply=less demand, the value drops.
Now if more countries ban, and there are fewer exchanges per country and the people have no way to use Crypto in everyday life (bread, petrol, etc) then the values will continue to plummet.
That said, Crypto's are not going anywhere and will forever be relevant, the problem is the value is held by what people are willing to trade for it. If more people want it, want to use it to trade, then it's value will go up again.
If there are no exchanges (to convert BTC to rand, etc) and I want to buy something (bread) and the shop accepts my crypto as a payment, then it will always have value.
To conclude, right now, mining is profitable and if you can make some bucks now then do it. Especially since we have Luno and ICE3X to get our Crypto's as Randela's (provided you've gone through some other means like Changelly of converting your crypto's to BTC/ETH)
The risk, however, is completely unpredictable by anyone. Whether you'll get your 180+ days ROI per GPU (hypothetically speaking) is unpredictable.
It's a risk all of us miners and traders are taking...
