I think a 10-year period is enough to make it self-affirmative. I hope they will not be too bitter about Bitcoin and see it as a real currency. In addition, it is necessary for large enterprises, governments and banks to approve it
I hope that on the 10th anniversary of bitcoin, the main prize is the number of countries that accept bitcoin, because with the increasing number of countries that accept bitcoin means globally it has been recognized as a currency. Bitcoin does not need to be a major currency, but enough as an alternative to fiat money, both as a means of payment and investment.
