It should be painfully obvious that the mission was completed for the time being. People in addition to Bitcoin have created something from relatively nothing. After the cost of equipment and energy, the coins are minted. Currently there are about 50 altcoins that people want. If you give them enough, they will trade them for BTC and get fiat cash for them. The possibilities for hundreds of thousands of people benefited by this system is only limited by one's altruism in teaching the needy about them.
The question is, how to get them without paying fiat cash needed for bills, toys, charities, etc. and how to keep them working.
your definition of wanting as bit weird to be honest.
people don't want any of the altcoins, they just trade them in very short terms to make more money. that is all. so if anything they want money not altcoins.
and the possibility of profit is not for all the hundreds and thousands people who are trading these altcoins, the profit is only for a few who know how to survive in this market and the majority who are losing money consistently.
