Yes but unless you won a large amount of BTC like >10 BTC or so it shouldn't be considered that you are a winner with such a small winning amount. Its easy to gamble small and win small. So small bets don't count.
10 btc is not really large for some big whale. 10 btc for ordinary people is really a lot thing but to get that big winning I dont really think that you dont need more money to earn that. Which is some ordinary people could not afford it so if you want to aim big better save more money before you do it
Exactly once. To get the big advantage we have to have the funds anyway. Because if it were not so, then we will get a little obstacle to win big. 10 BTC for me is a pretty big victory and it requires a strategy that is robust enough to get 10 BTC. And I think if you want to correct large should better not have done, if you just have a little funds. But if you have a good strategy and a little Fund most likely you can get a great victory, it's just that it takes time
