For all you have mentioned aboved there are others but commonly these are employed. Before I am joining launchpool in binance since I hold bnb and thats a good profit for me. Well thats the thing its really a passive but since I dont hold now I resort to some like liquidity and farming which give some good tokens.
Crypto still risky so not all are solid passive income. Maybe try some staking but that depend on the price too if its going down.
Since the staking is done on a CEX and with coins controlled by the platform, for me it is more risky than the potential profitability of this staking, and it also depends on the person's capital that he invested in these coins. HonestlyI tried this before, and I do not see that its profits are worth the effort and the period of time that I allocated for staking; as the market is volatile, it is possible that the profits will be erased with the decline in the price of the staked coin, and also CEX is not reliable for holding crypto for extended periods. In addition to the price of one BNB coin is now $700, which is $20 below its ATH, it requires any investor to have a good amount of capital to risk, which contradicts the principle of investing what you can afford to lose.
These platforms entice investors with the features they offer for their coins, which increases demand. Still, no one can guarantee the impact of negative news about the platform that could directly affect the coin's price and the invested funds. From my observation of the trust associated with Op, it seems to be a "Shiller" for these exchanges, and a person should not be driven by his greed without calculating the risks associated with his decisions.
