That is great but I wouldn't advocate keeping them on an exchange for getting new coins and the reason is because you never know if the exchange will be up the next day or not. I don't know about you but I would rather my bitcoin be safe than it be on exchange and have it compromised for a few hundred bucks. Although my friend uses Binance and apparently he got some Super Bitcoin and something BCX the other day too so not all bad.
That's my dilemma. By keeping the coins in my ledger, I'm not getting the drops from Binance due to no BTC (or little amount in there). To date, I have 0.000001's of BTG, SBTC and BCX since I have a trace amount of BTC left in there etc...and not sure if the risk is worth the possible reward.
