In the period of 2016-2017 I was quite persistent to get more Bitcoin because it is easy to get Bitcoin from various ways that can be done.
I participated in dozens of bounties and airdrops, and I was really focused on that time, until I finally got an airdrop that gave me a profit of 3BTC because of the incredible price increase and some bounties that gave me a pretty big reward, and then I bought Bitcoin.

I have never participated in bounty campaigns, but I was seriously involved in faucets and of course sig campaigns - so even though your 3 BTC seems like a lot to some, they may have forgotten that 1 BTC during 2016 was worth between $380 - $1000 at the end of that year. This means that here we can talk about a max profit of $3000, or maybe more if some of it was achieved during 2017.
Today, 3 BTC seems like a lot of money, but before that was not the case, especially during 2015 when 1 BTC was worth just over $200.
