What are the purposes for putting money in banks which will only give you 7-8 % annually, when you can invest that money in BCX getting up to15% per annum for staking? And on top of that you will also earn additional BCX from the Block rewards and gas fees
There's assurance in the bank.
And we're not all the same that would like to prefer to the volatility of the market. So those people that likes to time deposit their money on the bank, that's what they prefer as it seems safe for them.
For staking, I'd rather prefer to have stable coins on an interest account.
