yes, I did the same thing. but I prefer to buy bitcoin and trade with several pairs, such as BTC / USD.
but I've read a number of posts that a new project will appear with an old token that is dead, is this true?
Depends what them team to do for new project development. sometime project make such thing glamour as old them have before, they want to make some new point to make it possible to everyone. how about pair btc/altcoin?
