I read some criticism around Bitcoin, because is too volatile, but this is the reason for the success of this crypto ( and others), imo Also, why do you need a stable coin ? If you can't pay with Bitcoin for you coffe, who cares ? I mean, it is just like gold, you don't walk around paying with gold, but you know it has value. I just can't see a clear disadvantage on being too volatile, something that could make ppl loose interest on Bitcoin. I would like to hear opinions on that.
For bitcoin to work as an effective currency, it needs to be stable. The reason why there aren't that many merchants around the bitcoin ecosystem is because they are scared to receive a payment that's too volatile. Bitcoin would have been an excellent currency since you can use it across borders without having to exchange to a country's local currency just to buy something, so there's that.
