I do not know who would sell Lemonade for Bitcoins because I would not do that because I do not think that I would make much money with it at all.
This would be a good thing for kids who want to make money.
I also think that this is not very smart because you cannot make a lot of money with doing this, and its also that not a lot of people will buy it with bitcoins.
This is a useless idea in my eyes.
Yeah it may be a fun idea but we know that something like is is not going to work at all I would rather gamble then stand outside and try to sell lemonade.
I think that you are going to make max $1 if you are lucky.
