It all depends.

In 2016 I invested 800$, got it 3 times back in 2017.
With the return I invested 2000$ wich is not paying out anymore.
I took screenshots from time to time and for example in january 2018 at the peak of Bitcoin
the revenue was somewhere around 35$ a day.

From my point of view they should continue mining or at least are doing in now without paying their clients out.
At a time Bitcoin will get interest again and I'm pretty sure it will rise above 20K.

That said, If we keep mining now and price goes up big again soon or later.
We can make much more profits but.. I really understand why they do this.

Let us say 1000 investors want their payments and BTC goes to 2k.
They can actually go broke and everyone is losing their money.

In the end I'm still running my GPU rigs on solar energy on ETH wich are mine due to the above fact.
I will pay the extra energy if needed from some savings I made before to overcome the dip.

Let's keep positive here. The power of blockchain is huge. For instance gaming platforms that are getting developed now.
