I started joining airdrops early last year when I became a junior member in this forum but I joined a lot of them but only few is giving me coins and must of them aren't just hitting cryptocurrency exchanges and more likely were scams and bogus coins.
After the first quarter last year I stopped joining airdrops but instead diverting my focus on signature bounty campaign because I received massive number of coins every week and turned them into real money that could buy everything I need.
