When is enough enough for you?

At what point would you cut your losses and just call it a day with the entire crypto space? If, like me you are convinced (or have convinced yourself lol) that there is place in future civilisation for these networks and the ability to transfer “wealth” or “money” or whatever via them how many years of say, not exceeding the current all time high prices for your chosen coin/coins would it take for you to accept that the prices are ultimately where they are and that the returns you hoped for aren’t going to come - even if we reached mass adoption for example?
