With 10 bitcoins you could buy a house in my city, not a big one but a house... Is hard to end with profit in gambling and this is mainly for the fact about: 'We don't know when to stop', if we are in profit we are feeling lucky and that pushes us to bet more. So, to end with profit we have to play it really smart. No one say it would be easy but is possible.
of course if you want to follow the plan then your losses won't be too big and you can also save your profits?
Lol. 10btc at it's current value can alreadt get you further in life. The horror if you think about what btc's value may be once it makes a move upwards. If it breaks it's current ath at almost 20k, imagine how much your lost 10btc would be worth. Quitr depressing eh?
I am pretty sure that he has much more than 10BTC in his wallets. Otherwise you wouldn't stay that calm if loosing 10BTC with gambling. Maybe he holds 100 or even 200+ BTC value in crypto. If so it still remains a hit but on the other hand he probably can afford to loose 10BTC.
Beside that did he lost 10BTC in deposits. You can also depo 1BTC work it up to 10BTC and then bust everything later on
winning is not a big matter in gambling but sustaining with the profit will be the most difficult situation for example why I am saying this if we get lost from the gambling we need to regain it from the next gambling but it will not happened for anyone but showing this kind of losses will happening still now.
