Are there really people going to store their coins to these kind of sites that offers Annual Percentage Yield?
I'm not sure because even when Bitcoin is in my personal wallet the price could go up anyway. I can only see people would rather trade BTC themselves than storing to such sites though.
I'd be interested however if they and Freebitcoi.in will also offer APY in bear market.
Freebitcoi.in offered 4.08% in late march of 2017.
Nexo offered their high interest savings APY% sometime in 2017. Doesn't show an exact date.
Defi looks like within the last year or so. Early 2019 is when they started offering their services.
Cred Earn appears to have been created within the last six months.
I'm not sure if a pro-longed bear market would affect these sites. It seems most offer some variant of fiat currency to invest in also. So maybe when fluctuations happen in crypto they hedge it instantly with their local currency.
