well, OP is anon so he/she could have many reasons to share it here
from building reputation to making connections... maybe?
here is a good place to find like-minded people in terms of gambling.
I wonder if you are able to win hundreds of thousands of dollars, then why do you need a reputation anywhere and any connections? Why do you even need publicity? If I was capable of making that kind of money betting I wouldn't brag about it either in real life or on the forum, I can't think of any reason why I would want to do it.
everyone has a different view, in my opinion when someone wins a very large amount of gambling there is a sense of pride in what has been obtained until they decide to publish or for other reasons such as wanting to motivate friends in this forum to decide to post the number of wins which I think is very large for a parlay game.
for those who play parlay, the level of victory that will be obtained is very small where we have to choose several matches and have to win all of them, of course it is very difficult and when someone manages to win it is very natural I think he is proud of himself.
that's the result he's got but we all here probably don't know how he's been through the previous days, I think what he's got in 2021 is his luck which is very difficult to repeat.
