ADA is a cryptocurrency that's tripled in value the last month from .40 to $1.24, currently. The article is just saying while you don't want to spend the currency right now because the value is going up, the author doesn't think the value will ever top $3 and that for ADA to actually be useful, we should want it to be a currency you won't just HODL (hold on for dear life, meaning to invest long term) but actually spend.
