Considering the fact that you are from Bangladesh
I had a different country in mind, this makes the average salary even lower. Quora puts it at $157 per month on average, averagesalarysurvey.com makes it 10 times higher for high paying jobs. That makes 20 Bitcoin worth many years up to a few lifetimes of labour.So we can assume that his entire family tree is now having a lot of money spend and enjoy their lives for at least a decade. Also since he is trying to gather more people to follow his kool-aid crew we can assume he will continue his methods of promoting ponzis.
Speaking Bengali doesn't mean he is from Bangladesh because in some part of India too the language Bangali is in practice so he maybe trying to help some Bengali's not bangladesihs! Or he just did for some merits.
He IS from bangladesh. This is proven by the fact that his brother himself is also another Bangladeshi and so is his wife. Stop commenting without having gone through the entire Investigation thread on the OP and his brother (mahimonliner)'s ponzi promotion propaganda on youtube and which has been posted in this forum. 
Bottom line is that the escrow offer was ill-conceived at best.
Offering an escrow without prior trades is an attempted scam. This much I have learnt from being here for this short period of 2.5 years.
