I have a question about leaving my money inside an exchange. It says i will earn 15% annually if i leave my ethereum inside the exchange. so if i have $80,000 worth of Ethereum. I will get $12,000 per year for leaving it in there? My exchange is Hotbit.io and it actually got hacked recently. But yeh. I heard coinbase offer this too. im not sure. Is this APR thing Good??
Your APY calculation is correct, and usually Staking on an exchange has a limit of participants, not everyone can follow it.
By the way, like the above people you have to be careful leaving money on an exchange because we will never know what will happen.
