I wish high frequency trading was allowed, I'd sell at $285 happily
well it wouldn't be fair to give every new player 100 USD while BTC went down a lot.
You would probably complain that you had considerably less money when BTC was at 500 USD right now and most of us gained from the rally
That's why we use the median score
But we will do regular activity checks. I have something like this in mind:
If no confirmation within 48 hours by posting in this topic, peoples balances will be "charged" with 1%
That means you can't HODL your BTC or USD without "actively HODLing"
edit: no confirmation is needed if at least one trade was made 48 prior to the activity check
