I work in finance so I understand that a 20% annualized gain is already a ridiculous amount.
I have however seen players doubling, tripling, 10xing their money through a variety of ways of which I can list here:
-Bitmex, Deribit etc. Perpetual Futures leveraged trading (1-100 x leverage - SUPER HIGH RISK)
-ICO/IEO trading (4-5 returns, MEDIUM RISK)
-Spot Trading (BTC/USD, MEDIUM RISK)
-Deribit Options (MEDIUM RISK)
-Cross Exchange Arbs/DEX Arbing (Buying alts on Dex before exchange launching on Binance - requires insider information)
-Gambling Games (Dice, etc.)
Does anyone else have any ideas to share or methods that consistently gives them good gains?
You've pretty much listed everything down, except for maybe how you can do ICO/IEO "investing" instead of trading.
Also, theres this thing you can do on the freebitco.in where they promise to give you like @ 0.02% interest per day. Computed, thats like 7.2% per year. I'd say it's also high risk since they can simply close down the website and run away with your money and you have nothing to chase them with.
