So what do you think? Will Bitcoin always remain a pure store of value, or can it evolve into a genuine source of passive income in the future?
I think the growth of its value is what you can consider it as a passive income. But you'll have to sell it for you to take profits. Otherwise, you're only see paper gains.
I have not seen any Bitcoin staking platforms that pays in such ways that I mentioned above, so for that reason you have to accept Bitcoin for what it is, that is a store of value, where you need to exit a portion anytime you want to take profits.
In centralized exchanges, they offer around 1% I think and the highest could be near to 5%. But I am in no way going to do that.
The custody of your Bitcoins will be theirs once you try to hit that 'stake' because you're only lending it to them and not staking it because Bitcoin isn't a proof of stake.
