I agree with your analysis, buying at any price works only on some selected stocks/crypto's.
Steem has the same potential if you ask me, 1,-, 1,50 or 2,- are all cheap prices if Steem goes up to 5,- or 10,- USD!

But then again, how low can the Dollar go? Do we even measure wealth in Dollars in the next 5/10jrs?
