As long we've realized and learn our lesson, I don't think it will happen again. It happened to me before, I thought that I can earn for a living through gambling after reading some articles about professional gamblers who make a lot of money through sports betting and playing poker. But trying it first hand is really different and you will understand more once you are losing, as the time goes by I realized that it's not for me and I can only play to past time but not alternative for to earn money.
You can do something for getting earnings only if it is potentially possible to earn it stably and the only thing is available for you is investment into something that has been proven as good investment assets like Gold, Bitcoin, and Stock index. Let's say, stock index can rise stably over long time and it is safer than a single stock asset that can fall considerably in price and even delisted or die with time.
Same with cryptocurrency market, there is only one asset there which is safest for investment and your fund, it's Bitcoin. If you want something more, choose Ethereum and perhaps one more as BNB or Dogecoin.
Why Dogecoin?
It's a Proof of Work altcoin.
It's widely accepted on online casinos.
It has been proven its survivalability over many years and market cycles.
It is a secured blockchain, see
