As of now, more and more users are getting the hang of sitting by their computers all day and they get paid millions through the help of bitcoins. What they earn is more than what they had in real life which makes life convenient and easier.
On the other hand, bitcoins are really helpful and accessible to everybody or to a group of individuals and they just click and their wallets get full. But what if, sometime in the future, bitcoins become more private and unaccessible? Will that cause a problem? What could've happened to us who were engaged in it first rather than the newbies to come?
I also agree with your view that Bitcoin trading will be more and will be slower. For that reason more and more Altcoins are born and will compete with Bitcoin like ETH for example.
Wow how many are earning millions though aside from whales who already have a lot to begin with? The future that i'm seeing is that there will be a significant connection of bitcoin and governments through certain regulations, thus making it more accesssible to majority of the public. Alts will also gain more attention and acceptance so in general, the market itself will be more mainstream.
