Is Bitcoin's simplicity and security enough to keep it ahead, or do you think another crypto might take over in daily utility or adoption?
Yeah the utilities that Bitcoin have are enough to keep it ahead, other cryptocurrency can offer better in daily utility by using their centralized network which won't cost a lot to confirm transactions. Many people also prefer coins with stable value instead of volatile even it gives them advantage in the long run.
A decade is long, we might see something new, but I'm sure Bitcoin will still dominant in cryptocurrency.
