No worries mate to be honest I'm not sure what they count as "suspicious behaviour" but buying your BTC in one go and sending it a personal wallet address will just make you look the same as every other buyer on their exchange :) (making multiple buys in a row might flag you eventually).

Only other thing to remember is there are transaction fees for paying from your wallet, select "replace by fee" in electrum and turn the sat/byte down and it will only cost pennies (sounds complicated but when you get your wallet you'll see it's easy, just one slider!), just make sure you buy a little extra btc to cover it!

Enjoy the smoke mate!
