Just tell people you’ve had some bitcoin for a while... perhaps feign some disappointmemt that you didn’t cash out earlier. No one needs know how much exactly. Perhaps you’re still holding or actively trading some crypto assets. Unlike doing well from say a startup or getting some nice bonuses in finance etc... crypto is rather vague and others can’t really infer just how wealthy you might be.
There are people out there with say 50 million in assets living in large homes next door to people who have mortgages.
It doesn’t cost much of your win to get a big house with some land, a pool, cinema, gamesroom and plenty of garage space.
No one even needs to know about the London crashpad you use when taking the Mrs to West End shows etc... or the big villa on some Caribbean Island.
I think it's different for different people. For most young to middle aged english guys their social lives revolve around their mates and get involved in the community and family. It's pretty hard for them to keep quite a big win because they won't be able to do whats necessary to survive and be happy being incredably rich. And thats to mostly cut contact with everyone apart from the core family. You're going to get begging from extended family and friends of friends.
I'm a lot different. I'm a bit of an isolationist, i only speak regularly to my core family and basicly have no friends (and i keep that way and enjoy it) I'd only give money to my brother and his family, my wife's family and my mom and dad. That's it.
My mom and dad hardly need it anyway, they're in there 70's and have a great pension and everything is paid off (no mortgage) and no debts, they're very happy in their home and don't want to move, so all i can realy offer them is travel 1st class to whereever they want to in the world, which is not many places. I'd say they can live like kings for the rest of their lives with £500,000 at the very most.
My wife's family would be pretty stright forward and they probably use it to setup more businessness, seriously not only would i give them enough to pay off all their debts but i can invest in the family and probably double it in 5 years
My Brothers family is the difficult one. He is a bit of a dick and any amount i give him, large or small, he won't be happy. But what i worry about the most is my sister in law. She herself is fine but her family is almost the sterotypcal chav irish family. The kind if you throw them a penny they'll banging down your door everyday for more. I could just give them a couple of million just to watch them tear themselves apart and it would happen very very quickly. They haven't given me 5 mins in the last 25 years but i would bet if i won and they found out they'll be ringing me every 5 seconds like they're my new best freinds.
Keeping it quite would be easy otherwise, i've already got a decent sized new house in a decent area. I'd probably get it redecorated and buy a luxary family car and a little runabout but that would look out of place round here. And things get too hot i can ditch and move to a nice part of london and change my mobile number. with a win that size i'd give most away to charity and spend my life making sure it gets used properly.
