Not that much actually. You can already be the house by investing in a trusted cryptocurrency casino.
Crypto-Games is one example and here are their minimum investments:
0.01 BTC, 0.25 ETH, 0.5 DASH, 1.0 LTC, 1.0 XMR, 20,000 DOGE, 25 STRAT, 50 PPC, 0.1 BCH, 15 GAS or 5 ETC
When you're an investor you are technically speaking the house.
Though, you should stay away from any website that offers leveraged investments, that's almost the same as straight up gambling your money.
Owning some shares of a gambling sites is the easiest way to become a house though its not that profitable but at least its hassle free and affordable. Bigger capital need in this kind of ambition, you can dig more on your goal but always set a goal that can be more reachable and possible, always be more realistic.
I didnt think of this one but the idea is really good. Even though the profit is not that big, the stress is also limitted and i can focus on other things and maximizing my time. This also can be a good starter for any business plan.
