A number of bitcoin like cryptos are still sticking to their lowest. I think people need to invest in the coins they think are best for their interest and would stick to it for a longer period to get returns like bitcoin. But as you said in the downside section that simply investing in the coins does not guarantee you the returns, so people should be making informed choices and maybe most of them will earn the "Generational Wealth".
I think very few will, but some likely will, bitcoin has probably the best chance of any due to several factors, including its name brand.
I saw a few posts where steemit was mentioned, one of them was posted on a reputed media platform, showing the upside of using decentralized social media platforms and earning incentives for doing so. I think if people invest in steem before the release of the SMTs then only it will be a good chance to get massive returns from steem currency.
It could for sure. Steem just needs to increase its user base. If it can do that, the price will take care of itself. Not many apps in crypto have large users bases currently.
