So, we have all been told to keep our coins in HW wallets and not on an exchange and I did that with the Nano S.  But, when I go onto Binance, I see that I got a super, super small amount of a "gift" coin or result from a fork with BTC but not getting that equivalent in Binance b/c the BTC is not there. Is there a value to keeping something on the exchange to get bonus coins or forks?
