Bitcoin is a more reliable crypto currency, unlike everyone else, and that's why I and most of my acquaintances prefer this crypto currency.
This is the main reason people prefer to hold bitcoin, even among the top 10 coins there are coins that I will never hold for the long term since I do not like several of their characteristics or some of the actions the developers of those coins took in the past, but when it comes to bitcoin I see an honest project trying to deliver on its promise to be a currency and a payment system used all over the world and that is why I place so much trust in it.
