lol, you must think only shitcoins or nft people can lose money, dude read what he said, he lost by trading btc (10 btc to be precise) I believe it was clearly written in the heading of the post.
Maybe you are the one who need to understand the post betterHe said he lost 10 BTC he didn't specify how? Did he say he lost 10 BTC trading Bitcoin?
People can lose money through btc too, most traders trading btc with less knowledge are bound to lose if they are not careful, alts are not the only way to lose money. 
Besides, shitcoins have also made several millionaires
And where have i said people don't lose money trading Bitcoin?Besides, shitcoins have also made several millionaires

This is where you people get fucked. You think everyone can become a millionaire over night if they trade shitcoins. If I may ask, if several are millionaires, they how many have got their life time savings and account REKT to zero
