no, as for me i didn't know.. friend of mine invited me there 1,5 year before and i invested there a little amount, something about 20$, and forgot about that, and one day before they scammed (june 25, 2016) i found 155$ in my wallet!! so i thought -it is amazing site! i must invest more there and i will get more!- so i did some resarch, i read a lot about hashocean, everyone wrote the best about this site and said that you can trust them! i didn't find any negative opinion about them in the internet!! so i invested there 100$ and the next day they scammed(((
This is called being unlucky you lost your profit plus $100 . If I were you I would withdraw 50% of money atleast before reinventing.
My story is also almost similar to your.
I also joined this site 4 days before but before i reach at payout limit the site hashocean had gone forever in hell .
