We can see these days that not all people know cryptocurrencies, if they do perhaps they have heard only about bitcoin, but without owning or having the experience of making any transactions.
Maybe altcoins will become popular within 3 years from now?
It will. I think it might take well in a year or two because alot of people got interested and curious about the cryptomarket and its not just bitclin tjey are talking about but also altcoins in which they have.chance to known too. as long as this coin is useful to us it will be known for sure, Its just a matter of time
