While you are submissive to learn in this Bitcoin journey, i will advice that you should mind how you interfer into public conversations about Bitcoin because you manner of approach can implicate you to risk amidst untrusted people especially strangers like that you just found yourself.
Don't just jump into conversations like that you are not invited.

Straight forward... let us talk about this guy that lost painfully on Bitcoin trading, before he ventured on that quest, was it that he knew Bitcoin was a scam and still invested his hard earned funds on it even in the consecutive basis of a straight one week trading? What was he thinking? To outsmart the scammer behind Bitcoin or to beat the house edge if it was a gambling resource?

Only the stupids or vulnerability to scam would ignorantly invest their money in anyway market or commodity without asking questions about how the market works especially researching to understanding the reliance and reputation of the commodity.
So if in reality your story is true OP, that guy was either scammed or he eventually ventured into the trading market with greeds mindset which paved him the Ignorant to question how the market works before he invested his money in the first place.
