Is there any 100% Safe investments? I guess no.
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.
