im scared to put money in this kind of sites 
its better if you dont, and you stick with known services like hashnest thats been around for more then 3 years at this point.
as for this site that just popped up like randomly like most of these do, you dont know when the operators decide to leave.
lol hashocean is only 1 year less on the market than hashnest and is simply not doing the Mining buisness with asics bro,
They are simply scrypt Miners. And in this kind of Mining its much more profitable if you got the right chips for it
It could be also possible hashocean could be a reseller of the sfards or something like that? How knows? ive simply seen the videos seening them putting radeons rx together in an Mining Rig and doing there Job on the Screen with 715 kh/s
So in my Opinion. Everybody is doing great with hsahocean. Everybody who is scare should just invest small Money and wait 3 months
