It is easy to get 10-15% ANY return rate, but the problem is that you will get that percentage in the form of altcoin and the value of this token/coin may decrease, or you may not be able to withdraw it, or it requires a large capital that makes the risk of losing everything very possible.
This reminds me of the exact same discussion with someone thinking high APY in some shitcoin is better than banks:
One of the crypto's with interesting staking returns is #ICP¨, as it can give you uptill 28% APY (yearly).
Sounds better no?
Wake up people, before you end up poor!
We will speak end 2022 if your 1% bank interest was better than investing with 28% APY at a low of 17 (in this example..., is not the only project I am staking)
Time will tell 
I nearly forgot about this till somebody pointed it out.
Seems like it's time to see the result:
So you had $17
- putting it in a bank with 1% you would have $17.17
- despite the last pump, your investment is currently $5.4 and with an APY of 28% is $6.92.
So not only you haven't made a profit but you also lost $10.08 of your investment of $17$
Probably a lesson that earning more money by just buying money doesn't work always how some wish it would.
At the moment the guy would have lost nearly half of his investment, right now he is even worse with his shitcoin being worth only $3.11 so despite the APY he would have ended right now with $5.1 versus the initial $17 and even $20 if we assume he would have got them invested in simple tok indexes.
Don't get tempted by high returns in shitcoins people, you will end up far worse than holding fiat, these are just printing machines on steroids.
