You bring up some really good points here that I think are very important to realize in this euphoria. What have many of these coins accomplished so far ? Because if we only judge them based on what we think they will do then that is a pretty risky investment. This point which you bring up I think is very important for each individual to reflect on.
Steem is extremely undervalued as it has proven it works for a long time already. It is also one of the most used cryptocurrencies out there I also agree with a hundred percent.
I think the top 100 on coinmarketcap will change a lot within the coming month. But the ones with the underlying technology will remain and climb higher.
Without a doubt Steem will be one of them.
