In the last few years of my active and drastic moves towards Bitcoin, what I have come to understand with Bitcoin is that, no matter how little your portion is, it drives its own units interest and likewise loses if when the Market either go up and down.
My few Bitcoin investment done using my leftover and other extra cash in two years ago have yielded enough interest
It is wrong to say that you've earned interest through holding Bitcoin. There is no interest on it by holding but you've made profit because its price has increased a lot compared to how much you've bought it. Just like gold, there is no interest in holding it but its value is increasing over the period of time.
now I comfortably own my own home through my Bitcoin this is exciting time for all the Bitcoinairs and knowing that after achieving a milestone we still have some Bitcoin waiting for the next big opportunity.
Congratulations to you. I am sure that there are many Bitcoin holders that have sold some for them to have a comfortable house that they'd call home. Continue holding and keep the faith, this is how it should be for most holders when the right time of selling has come but don't sell all you have.
