Came across this recently. BitcoinHEX seems to be the first high interest savings account on the Blockchain!
There's more to finance than currency! At your normal bank these are called CDs or time deposits, but they don't pay better interest if less people use them, we do! Let's replace all these middlemen with trustless interest! BitcoinHEX is a Store of Value. 369%+ ROI if only 1% of coins stake.
Here is a reference link to explore. https://bitcoinhex.com/?r=0xc7f2ab10d5a9b8f9261d7d397630da85fd684e65
