I agree with you partly, I do not think that steemit will be the best social network nor that btc will be the next currency.

These are just ancestors of the upcomming upgraded versions of these.

I also do not like how the system with bots works but I think that as soon as you have your community of lets say 1k+ active followers you do not care about bots that do nothing. Because those people also invest in steem currency.

Now it is one of the best times to invest in it actually because the higher value your account has the bigger influence but also if steem goes up the investment will be worth it.
