The bitcoin does not provide good interest.
We must understand that bitcoin is not a make money scheme or bank scheme to offer us good interest. Its a payment system which is better than fiat so in other words, its just a kind of money which you hold with yourself. There is no point to ask for returns if we are holding our money with us (no matter in what form).
However, being in the early phase there are lots of growth opportunities in terms of price appreciation (which we have experienced sine 2010) and hence I think, it is better than interest.
I would agree, mostly but not all, people forgot what bitcoin basically, there's no free worth bitcoin just a dust which can earn from captcha and wasting time.
Also mostly forgot how real work, means bitcoin is just a currency form, also same as another currency when you want to earn it you must work for it.
But that is now, when bitcoin began as nothing more than an experiment, people mined bitcoin, and received free bitcoins for doing nothing or in giveaways, so at least during the early stages of bitcoin development people could earn bitcoins by doing nothing, obviously bitcoin at that time were not worth much but now those people are enjoying the money they earned.
