ask yourself why you want to buy into this scam in the first place, is it fomo(feel of missing out)?
or did you think the tech is irreplaceable?

to understand what is eth i probably can do some dd for you.
what is smart contracts? smart contracts is simply a hype butterin vitalik use to lure people into this platform, he copy idea from nick, https://en.wikipedia.org/wiki/Nick_Szabo
etherium and the whole scam platform is code by this person in a few months; http://gavwood.com

is ethereium platform worth something? yes, but in by book it is worth less than $10million if we talk about the old day hard earn money, minus the crypto wild wild west scam hype. the bugs, scalable, bloat and centralized issues this thing shouldn't worth more than $5million.
