I don’t see how question 1 is valid. You just move the coin immediately after acquisition. If you’re speculating and leaving them on the exchange that’s risky.

But as far as “obtaining” the coins, you simple have to be in control of the keys. This can be accomplished within minutes or hours after purchase. Hence not your keys, not your coins.
