as far as "legitimate" ways of making ridiculous amount of profit in ridiculously short amount of time go, there has always been "legitimate" ways of doing it BUT  they have always been also ridiculously risky.

i don't know any of the things OP is advertising but they do exist and you can also lose all your money in them as the shitcoin you are staking dumps or maybe is buggy and shuts down.

another way of making such profit is shitcoin pumping. here is a random list of some random shitcoins sorted based on their pump in the past 24 hours. ignoring the first one you see 25000% profit in just one day!
