If the bookies will allow that kind of huge amount of winning then it's possible.

But imagined how tough and difficult to win that kind of huge amount, especially in sports betting since that was only possible if;

- will bet a high stake
- forming multiple parlay legs to achieve an insane high odds


I think in some countries, their respective national lottery can be purchased online.

Referring to crypto-casino, I think the lottery is something, not that demand here or being supported. Never seen a crypto-casino doing a lottery offering such huge amounts that were close to the figures stated on the main post.
