First of all you shouldn't take investment advices from anyone in the crypto space unless you're 110% sure that they've never been involved in fraudulent activity and have a solid track record in recommending profitable investments. Even then you shouldn always do your own research on the project or doing your own technical analysis, and only after that decide if you're still on the same page with the "advisor". In cases like this you unfortunately have no one else to blame but yourself, take this as a lesson.
