That's how I feel about it.
It's like you gotta have a lot to get a lot back. With the low amount of XRP I have, I'm lucky to get a whole XRP coin after two weeks at these rates.
That's why I'm testing just lending out the BTC because the lending rates for BTC are significantly higher than the rates for lending out XRP.
With 1 BTC being worth like $1600, I'd rather grind the lending game to work towards getting a whole BTC coin than a XRP coin.
I feel like if I have several active loans of BTC going, all with decent rates, I could probably get a whole bitcoin in a little over a month.
