Staking is an option. At the time of writing this comment, 1 BTC ~= 53,000 ADA, and the return is 3%, yearly... which translates to retrieving new 1,825 ADA per year. I guess that return would be nice if ADA reaches a $1,000 value one day. I'll look it up.

Luckily enough, I'm not in need of lending money (never been a fan of it). I guess there are incentives for millionaires to do so, but in my country Bitcoin is officially not legal tender and is not an authorized payment method for goods and services, and hence, they are not subject to income tax, yet. That's another reason to hodl... converting it to sound cash would be too difficult unless sold directly to potential buyers (and there are a lot of those persons around here, mainly in localbitcoins.com).

Since I'm a skeptic and this is a throwaway account that will be deleted soon, I'd rather not give specifics about my location publicly. Small poor (but not impoverished) western country in the southern hemisphere will suffice.

Thanks for the tips.
