Nothing in the world is guaranteed,
Especially in the digital world when the chances to get scammed are very high.
Personally i invested, got profit, reinvested again and got scammed ,
But investing is good method to grow your bitcoin but you just need to look where are you investing at.
Well never heard of that website in the past,
But personally i invested a lot in cointellect a "cloud mining" company which was working perfectly and the number of users was increasing exponentially.
I have lots of data still on my archive but i will not invest in the future in these kinds of websites, so not a good method to grow your bitcoin.
I though that it was somewhere in europe,
They were listing in the map and somebody confirmed that they had offices there,
But the mining farm was located in china, but at the end this is not important as they disappeared.
To stay on topic, i will never invest in cloud mining to get profit(grow the bitcoins) as it is very risky.
Well to my friends and to my relatives i don't recommend dice/betting/gambling.
Because it is to dangerous, maybe not the amount of money risked there,
But one day it can be addicted and most of the time your lose money and not growing it.
