I do not think spreading out a few bucks worth to a ton of people does anything. If I had 10 bucks worth I would not be incentivised to work hard to promote or adopt I would likely just think thats 10 bucks I can cash in now or just leave it for another day and likely forget all about it.
It is not just 10 bucks if the user becomes active referrer and brings in more people. Many of the distribution methods have referral system, which gets improved to a new level with every new distribution method. Bytes are not airdropped for just linking your address anymore, one needs to put some effort in and grown the community in order to earn more. Those who put more effort in it are also more likely to become real users than those who got just 10 quick bucks.
