I think its unfair to compare it to a search engine, since each token has a unique use case, although I do think that adoption is key.
But I also think that BTC dream died when 1000 investors can sway the price in one day.
I think a cryptocurrency must have a balance of inflation like that of Stellar where it is not like a loyalty reward like NEO has for POS but is enough to equate for inflation for that year.
just my .02 cents
