He bought 100 STEEM of me yesterday and we sent it to his account to start with and he wants to gradually buy some more. (the way I always buy).
If he is able to keep this up and probably get up to 5k, he could delegate his SP to another user and watch his return come in, in form of steempower.
With this, he never need to blog and he is already an investor getting his return weekly or even daily as the case maybe and with the current price if steempower means more reward to him.
His money kept safe and still getting profit literally doing nothing.
That's one of the many benefits of the steem blockchain
