You have a point there, it's an amazing win but I think there's a loss also that has been hiding by the OP.
It's impossible that OP doesn't lose on the way. It's just that when there's an attempt of promoting a service like a tipster, posting winning is what matters. And besides, the summary of the amount seems legit. That's a big win and no doubt about that.
To add some spices for the supposed promotion, if ever there's a tipster service involved here as I didn't check yet OP's Telegram, might be better to have a daily shown of results.
losing is not the biggest problem if we limit big losses
as in trading gambling has 4 kinds of common outcomes
big win
small win
big loss
small loss
if we limit big losses we'll make money on the long run
one can consider breakevens as small losses since they lose time.
Ohh I somehow disagree with your statement. While gambling may involve the four (4) outcomes you mentioned, the problem lies on its unpredictability. While OP did indeed won $550,000 on his pocket which is rarely experienced by a few, it is however implied that he had prior history of betting large amounts of money in the past. Even if we did limit big losses, there is still that issue of unpredictability which is innate on the nature of gambling itself.
I remember that my brother used to gamble as he integrate the martingale system. Though he won large amounts of returns in a single night, there were also some days where he lost more than $1500 on a single bet due to such crucial system.
