Very true @vieira.
We are very early in this game and a lot can change. For years we heard how Bitcoin is digital money and, to a degree, it is. However, it does not appear that it will be everyday digital money. Therefore, something will have to step in. Is it a known token, one that will be developed, or, I as ultimately believe, a combination of many tokens being used for many different purposes?
The last thing you said is what is having, at least from my perception, more prevalence today, after all, it is a decentralized trading system, it does not have to be reduced to just one cryptocurrency.
But it is still a very new market, there are still many surprises and unknowns, as well as many possibilities.
