[Feature Request] xDayThreashold per coin or based on market analysis

[JCBauza]

Hi,

So, usually some coins have higher rates than others. For example, USD is always around 0.08 on bitfinex while BTC might be around 0.03. So, in case of BTC a 0.07 rate might merit more than 2 days while on USD I might want above 0.10 per say. So a per coin setting would be nice

Now, how about we link it to the market analysis. I really don't know how it works so I am going to make assumptions to try to get the point across. So, we know if a rate is 1 to 99 percentile of the market rate. If we lend for 2 to 30 days max on Bitfinex per say, then we do a scale. So if rate is from 1 to 3 percentile then lend at 2 days. If 4 to 6 do 3 days, If 7 to 9 do 4 days, and so on... so if 97 to 99 percentile do 30 days. You can maybe adjust and do 1-50 percentile equal 2 to 30 days for example. Or if we are doing a 50 pecentile lendingStyle then do that as the lower bound. So 50 to 99 is 2 to 30 days in the scale.

Hope you guys like the idea!
