2. Staking isn't giving huge returns but staking bitcoin or Tether with APY over 8% is somewhat profitable.
If you mean wBTC, I don't think the risk that defi possess is worth the amount of 8% APY, not to mention that it is also far from the true Bitcoin, holding bitcoin on its own network would give a better and safer return.
I mean still its bitcoin which posses less risk than staking a shit coin with APY of 10% but the value of that shitcoin can fall 50% overnight but I never recommended staking for anyone even with stable coins because 10.5% isn't really worth the risk, its better to day trade the stablecoin against BTC and make the same amount of returns in a month or two then just be calm for the rest of the months.
Even if both ways have the same risk, at least we can try our skills to analyze the market and buy any potential coins at the right time. While we are staking the other coins, we will face a downtrend of the coins and we can not do anything except just see the price is up and down while the staking coins will be there.
But we should let them decide as we will have different reasons for choosing staking or trading. Besides that, we also have different experiences and profit in different ways.
