So who was using CHA first?
ChanceCoin? or CharityCoin?

CHA=chancecoin
and
CHA=CharityCoin
The question is, who used it first?
No it doesn't matter. There is no copyright on cryptocurrency name.
There is many cryptos with the same name. You only remember the most important one.
In this case, CHA=chancecoin.
I never asked if it mattered. I asked a simple question that has now been dodged by not one, but two people now. That alone tells me the answer. I am just a confused trader that was looking at ticker symbols thinking it was the same coin.
I am well aware that some tickers are not copyrighted (and if they were I am certain it would not be known bc the simple act of looking to see if the ticker wanted was already in use had already been overlooked), but what fool would try to use the ticker "btc" for example? or any that is already in use, for that matter. It just works against the coin if that ticker is listed on an exchange as a different coin before you show up with yours. I could come very close to copying your exact username on this forum, but that would be ignorant.
I thought one of the main points of cryptos was being frictionless?
