Should I boycott $ in favor of €?

Mainly speaking of forex and investing, since the reserve currency be default is still in US Dollars unfortunately (so you can’t truly boycott America) unless Euro wants to become the new world reserve currency, but it won’t happen overnight. It's because I'm saving money but deciding on what currency remains stable whilst valuable.

Well, Euro is the second most traded currency globally: so it is inevitable: they have higher value bank notes that are more than USD (100, 200 & 500€) and the exchange rate reflects that 1€ =$1.15 while the reverse isn’t true ($1 = 0,86€). Should I invest more in Euros and avoid US Dollars outright?
